Emeka Chukwu -- Executive Vice President and Chief Financial Officer
Thank you, Sandy. Good afternoon, everyone. For Q4 fiscal 2019, net sales were $160 million an 8% sequential decline and an increase of 14% from the same period a year ago. Fiscal year 2019 net sales were a record and an increase of 7% over the prior year, driven by our diversified growth drivers in the IoT, data center and mobile markets. In Q4, shipments into Asia represented 74% of net sales, North America represented 18%, and Europe represented 8%. Total direct sales represented approximately 32%, and sales to distribution represented approximately 68%.
Our distribution business remains balanced with 53% of your total POS coming from high-end consumer and enterprise computing end markets, and 47% of total POS coming from the industrial and communications end markets.
Q4 bookings softened Q-over-Q and resulted in a book-to-bill below 1. Turns bookings accounted for approximately 45% of shipments during the quarter. Q4 fiscal 2019 GAAP gross margin increased 40 basis points sequentially as expected to 61.8%, while Q4 operating expense increased approximately 11% sequentially, due mainly to the lower accordance of a one-time benefit from reduction and the fair value of contingent earn-out obligations in Q3.
In Q4, GAAP interest and other expense was $548,000 and benefited from a $1.3 million gain on the sale of our investment, compared to $31.2 million of expense in Q3, which included $30 million impairment of our modified investment. The Q4 GAAP tax rate was approximately 49% driven by a discrete item related to acquisition of related intangibles. The excess tax benefits of Comcast exercising is remain in (ph) warrants, we drive our Q1 GAAP tax rate to a benefit in the range of 8% to 12%. We expect our GAAP tax rate for the rest of fiscal year '20 to be in the range of 20% to 24%.
Moving on to the non-GAAP results, which exclude the impact of share-based compensation, amortization of acquired intangibles, acquisition or disposition related and other non-recurring expenses. Note that as previously disclosed in our first quarter fiscal year '19 earnings call, we no longer adjust net sales for the impact of the Comcast warrant for any comparable historical periods presented. Instead, we have provided a separate disclosure of the impact of the Comcast warrants under financial statements in our Form 8-K filing and our press release. Q4 non-GAAP gross margin increased 40 basis points sequentially to 62.1% as expected, due to a more favorable product mix.
We expect Q1, non-GAAP gross margin to increase slightly as the benefits of improved manufacturing efficiencies are offset by a higher mix of high-end consumer revenue. In fiscal year '20, we expect our gross margin to remain stable, with an upward bias driven mostly by end market mix. Q4 non-GAAP operating expenses was $53.1 million down 2% from Q3 driven by lower variable compensation expenses. In Q1, we expect non-GAAP operating expense to decline between 2% to 6% sequentially as a result of lower variable compensation expenses driven by lower revenue. We expect our non-GAAP operating expenses for fiscal year '20 to be approximately flat to (inaudible) maintaining our investments in our growth drivers.
In Q4, our non-GAAP tax rate decreased slightly to 15.6% sequentially and we expect our fiscal year '20 non-GAAP tax rates to be between 15% and 19%. In Q4, cash flow from operations increased 22% over the period a year ago to $47 million or 29% of net sales. For fiscal year '19, the cash flow from operations increased 55% (ph) over fiscal year '18 to $184 million or 29% of net sales and represented a new record. Free cash flow was 27% of net sales for both Q4 and fiscal year '19 and in line with our upwardly revised target range of 25% to 30%. In Q4, our cash and investments was flat at $312 million and our debt balance was approximately $212 million, resulting in a net cash position of $100 million. We repurchased approximately 771,000 shares or $36.5 million of stock in Q4 and $2.4 million or $116.2 million in fiscal year '19 and our stock repurchase authorization now stands at approximately $181 million.
We expect to continue to use our cash to opportunistically repurchase our shares, make strategic investments and pay down our debt. In Q4, accounts receivable decreased 5% sequentially due to lower net sales and represented 46 days of sales just above the target range of 40 to 45 days. Net inventory in absolute dollar terms increased 4% sequentially and days of inventory increased to 93 days, which remains at the lower end of our target range of 90 to 100 days. In Q1, we expect the net inventory to be up in absolute dollars and days, our lower Q1 sales and expectations for higher sales in the remainder of the year.
In summary, we are pleased with our strong financial performance in fiscal 2019. Our net sales grew 7% year-over-year to a new record, while we grew our non-GAAP earnings almost twice as fast, a demonstration of a solid leverage in our operating model. Operating cash flow was also a new record, and we repurchased 2.4 million shares or 3.7% of our issued and our -- and outstanding stock in fiscal year '19. While the geopolitical and macro issues echoed by our peers is contributing to near term headwinds on the slower start to fiscal year '20. We will continue to focus on execution and believe the long-term nature of our growth engines positions us nicely for recovery beginning with the second quarter and strengthening into the second half of fiscal year 2020.
I will now hand the call over to Mohan.
Mohan Maheswaran -- President and Chief Executive Officer
Thank you, Emeka. Good afternoon, everyone. I will discuss our Q4 fiscal year 2019 performance by end market and by product group, discuss our fiscal year 2019 performance and then provide our outlook for Q1 of fiscal year 2020.
In Q4 of fiscal year 2019, net revenues decreased 8% over the prior quarter to $160 million. Seasonal inventory reductions in the high-end consumer end-market and a weaker global demand environment contributed to the weakness in Q4. We posted non-GAAP gross margin of 62.1% and non-GAAP earnings per diluted share of $0.55.
In Q4 of fiscal year 2019, net revenues from the enterprise computing end market increased over the prior quarter and represented 33% of total net revenues. Revenues from the high-end consumer end market decreased over the prior quarter and represented 24% of total net revenues, approximately 16% of high-end consumer net revenues was attributable to mobile devices and approximately 8% was attributable to other consumer systems. The industrial and communications end markets, also declined over the prior quarter and represented 32% and 11% of total net revenues, respectively.
I will now discuss the performance of each of our product groups. In Q4 of fiscal year 2019, net revenues from our Signal Integrity product group increased 2% over the prior quarter and achieved a new quarterly record and represented 45% of total net revenues. Demand increased for our PON products while demand from the data center and the wireless base station markets were flat with the prior quarter.
In Q4, data center demand for our industry-leading ClearEdge CDR platforms used in high-performance, 25 gigabit per second to 100 gigabit per second NRZ optical modules and active optical cables remained healthy. We also sampled our first Tri-Edge CDR platform for PAM4 interfaces targeted at 200-gigabit per second and 400-gigabit per second PAM4 optical modules. And initial customer feedback is very positive in applications which require the highest performance at the lowest cost and lowest power. We expect to see initial Tri-Edge revenues in the latter part of this year.
Our FiberEdge PMD platforms, which complement our ClearEdge and Tri-Edge CDR platforms are targeted at next generation 100-gig, 200-gig and 400-gig optical modules and also sampling and receiving positive customer feedback. Our FiberEdge platforms include linear drivers and TIAs that are partnered with industry leading DSPs and provide a seamless interface to PAM4 optics.
We expect to maintain our leadership position in the optical module market as data center customers transition from our 100 gig ClearEdge NRZ platforms to 200 gig and 400 gig PAM4 optical modules, using our FiberEdge and Tri-Edge platforms later this year with real growth expected to begin in FY '21. In Q4, demand for our PON products increased sequentially. Semtech is the PMD technology leader in the 1 gig, 2.5 gig and emerging 10 gig PON module market. We recently introduced several new PON platforms, leveraging our FiberEdge PMV (ph) technology that we believe will enable us to extend our leadership position over the next few years as the market transitions to 10 gig PON.
Our China base station business also remained healthy in Q4, driven by demand from both the 4G and 5G markets. We are excited about our prospects in the emerging 5G build out and expect these networks to utilize Semtech's full portfolio of high performance CDRs and PMD devices. We expect early 5G base station implementations to initially use our ClearEdge and FiberEdge platforms with 25 gigabit per second fronthaul and backhaul links and then transition to our Tri-Edge PAM4 CDR in FY '21. For Q1 of fiscal year 2020, we are seeing a much weaker demand environment, due to excess data center inventory, China market demand softness, and uncertainty associated with ongoing geopolitical issues. These issues are impacting near-term demand in all our target markets.
As a result, we expect net revenues from our Signal Integrity product group to decline significantly in Q1 on lower demand across all end markets. We do not expect this weakness to be sustained for more than a couple of quarters due to the ongoing expansion of hyperscale data centers globally, the global transition to 5G base stations and the acceleration of 10 gig PON deployments. We remain very confident in our strategy and our position in our target markets and expect all our target markets to grow nicely over the next few years.
Moving onto our protection product group. In Q4 of fiscal year 2019, our protection product group declined 21% over the prior quarter and represented 26% of total net revenues. Demand from the high-end consumer market weakened throughout the quarter, driven by year-end inventory reduction efforts and lower global demand for smartphones and other consumer equipment. Despite the softening smartphone demand, our design wins across all Tier 1 customers in all regions continues to do very well, and we do expect to see a stronger second half performance from our Protection smartphone business. We remain focused on diversifying our protection revenues by expanding from our strong position in the mobile market into the industrial market, which includes the automotive, IoT and broad based industrial segments. We expect our new investments in these segments will enable us to grow our Protection business in industrial applications, which are increasingly used -- using advanced lithography devices. As an example, we recently announced the MICROClamp 2492SQ, which offers high performance protection for controller area network buses used in automotive and industrial applications. Future Ethernet ports, USB ports and infotainment electronics within the automotive and industrial environments, will likely all require higher end protection.
In Q1 of fiscal year '20, we expect our protection business to remain soft, due to weak global demand from the smartphone market and weak China demand. We still expect that Protection Product Group to deliver growth in FY '20, despite the very challenging start to the year for our smartphone business.
Turning to our Wireless and Sensing Product Groups and Sensing Product Group. In Q4 of fiscal year 2019, net revenues from our Wireless and Sensing Product Group decreased 9% sequentially, but increased 22% over the same period a year ago, and represented 29% of total net revenues. Seasonally, lower demand from the smartphone and industrial end markets led to the decline. Q4 was another quarter of solid progress for our LoRa business. A few of the key announcements in Q4, included Veolia and its subsidiary Buds (ph) chose business -- Orange Business Services to connect Veolia's 3 million intelligent water meters in France over the next 10 years using the Orange LoRa network. Semtech's 12 6x (ph) LoRa transceiver platform was named the Analog Semiconductor of the Year at the Elektra Awards. And the LoRa Alliance announced that there are now over 100 global LoRa Alliance network operators.
These are just a few of the many LoRa related milestones announced during the quarter. In Q4 of fiscal year 2019, demand for our proximity sensing platforms decreased due to smartphone softness, following several quarters of strength. We do expect our proximity sensing business to continue to grow as we see solid design win progress across all regions, as global regulations drive an increase in the need for radio energy management on smartphones and other mobile devices. In addition, we also see an increase in the number of high-performance radios and an increase in the power required from these radios, which supports increased proximity sensing content in mobile devices in the future. For Q1 of fiscal year '20, we expect net revenues from our Wireless and Sensing Product Group to decline due to continued smartphone weakness and continued China demand weakness. Moving on to new products and design wins. In Q4 of fiscal year 2019, we released 28 new products and achieved 2,303 new design wins.
Now, let me comment on our fiscal year 2019 performance. In fiscal year 2019, Semtech delivered a record financial performance with total net revenues increasing 7% over fiscal year 2018, driven by strong demand -- strong momentum from our three business units. We also achieved a record non-GAAP earnings per diluted share and record cash flow from operations. In FY '19, we released 70 new product releases and achieved another new design win record of 9,317 (ph) new design wins. In FY '19 our Signal Integrity Product Group achieved record net revenues driven by record CDR, record PON and record PMD revenues.
Our Wireless and Sensing Product Group also achieved record revenues, driven by record LoRa enabled revenues and record proximity sensing revenues. Finally in FY '19, our Protection Product Group grew 3% to deliver a solid annual performance, as we continue to successfully diversify into new verticals.
In FY '19, Semtech's LoRa business achieved record results, with the LoRa enabled revenue increasing over 85% from FY '18 to approximately $78 million. In FY '19, we were pleased to exceed nearly all the metrics we targeted at the beginning of the year. These metrics included the number of public or private LoRaWAN network operators, LoRa network operators doubled from 50 at the end of FY '18 to over 100 by the end of FY '19. We expect at least 125 LoRa network operators by the end of FY '20.
The number of countries with LoRa networks grew to more than 70 countries from 50 at the end of FY '18. By the end of FY '20, we expect over 90 countries to have LoRa networks. The number of LoRa gateways, more than tripled to 243,000 deployed gateway, at the end of fiscal year '19 up from 70,000 at the end of fiscal year '18 and exceeded our expectation of 220,000 gateways. These gateways are now capable of supporting over 1.2 billion connected end nodes. We expect the number of LoRa gateways deployed to double in FY '20 to over 500,000 enabling a LoRa end node capacity of over 2 billion end nodes.
The cumulative number of LoRa end nodes increased to 87 million at the end of FY '19 from 50 million at the end of FY '18. We expect this number to continue to grow rapidly and exceed 140 million cumulative end nodes by the end of FY '20. The LoRa opportunity pipeline exceeded $400 million at the end of FY '19 with an additional $200 million of leads feeding this pipeline. We anticipate that on average 40% to 50% of this pipeline will convert to full deployment over a 24-month timeline. In addition, while historically some 50% of our LoRa enabled revenues have been from China, our opportunity pipeline has over 70% of the opportunity being driven from outside China. As these opportunities convert to revenues, we expect our geographical revenue balance for LoRa to diversify.
In FY '20 despite the broader macro concerns and extremely soft demand from China. We still expect our LoRa enabled revenues to be between $100 million and $140 million. In addition to the strong performance on our LoRa metrics, we also began to see a number of new exciting use cases. Some examples of this are Amazon's introduction of its Ring LoRa-based smart lighting system that enables lighting control and security around the perimeter of a home or enterprise targeted at the smart home and smart building segments. Comcast machineQ announcement with Victor to introduce VLINK, a smart LoRa-based rodent trap that communicates trap activity to its IoT network targeted at the smart home and smart building segments.
And Tata announced that together with Genesis Gas Solutions, they have won a contract with IGL in India to deploy prepaid smart gas meters using Tata's LoRaWAN network. We expect Tata to win many more smart metering contracts across India. While still in its early stages, Tata's LoRaWAN network is expected to eventually cover over 400 million people in India. In the future, we expect to see an increasing number of similar applications were LoRa's low power and longer range can be leveraged in consumer and industrial IoT applications.
This morning, we announced the release of our first cloud-based LoRa micro service. Our first micro service is a LoRa-based geo location service that is available to our partners and customers to use with their LoRaWAN solutions to track and locate their LoRaWAN devices using the cloud. We believe that this service will be the first of many that we offer and will provide further value to the LoRa ecosystem. We expect that LoRa micro services to grow to between $80 million and $100 million in revenues within the next five years, along with the LoRa Alliance, we expect to continue to drive LoRa to become the de facto standard for global LPWAN use cases. In what we expect to be a multi-billion unit industry in the next five years. Now let me discuss our outlook for the first quarter of 2020. Despite a marked improvement in our bookings in the last two weeks. Based on our backlog entering the quarter and continued softness from China including a 30% decline in our quarterly POS forecast from China and continued softness from the smartphone and data center markets. We are currently estimating Q1 non-GAAP net revenues to be between $125 million and $135 million to attain the midpoint of our guidance range or approximately $130 million, we need a net terms orders of approximately 40% at the beginning of Q1.
We expect that Q1 non-GAAP earnings to be between $0.30 and $0.36 per diluted share. I will now hand the call back to the operator and Emeka and I will be happy to answer any questions. Operator.
Questions and Answers:
Operator
(Operator Instructions) We have your first question comes from the line of Tore Sandberg from Stifel. Your line is now open.
Tore Sandberg -- Stifel -- Analyst
Yes thank you, and Mohan, can you elaborate a little bit on what you just said about a pretty sharp improvement in orders the last couple of weeks. Is that a broad base comment? Is that specific to China? And I'm also very interested in if it also refers to the data center market.
Mohan Maheswaran -- President and Chief Executive Officer
It's broad-based, Tore. I haven't got the details of how much refers to -- is related to data center, but I would say, it's broad-based, it's across all markets, all businesses, all regions.
Tore Sandberg -- Stifel -- Analyst
Very good and could you also update us on the LoRa pipeline, what you're expecting for maybe fiscal '20, obviously it stood at $400 million plus in fiscal '19. Do you have a number for fiscal '20?
Mohan Maheswaran -- President and Chief Executive Officer
Yeah, I expect it to end at $600 million in opportunity. The $200 million of leads, as I mentioned, that are in front of the pipeline, I expect to convert to opportunity. Some of the opportunity obviously will become revenue, but we see more and more leads emerging. So I would say, by the end of FY '20, we'll be somewhere between $600 million and $700 million in opportunity.
Tore Sandberg -- Stifel -- Analyst
Great, thank you. I'll get back in line, thanks.
Operator
Your next question comes from the line of Craig Ellis from B Riley, your line is now open.
Carlin Lynch -- B Riley -- Analyst
Hi guys, Carlin Lynch here on for Craig. Thanks for taking our question. I just wanted to get some more clarity on the data center business in particular as you -- how you guys see that playing out in the second half of the year. I know you guys had talked about a bit of an inventory digestion in the first quarter before, and I'm just wondering if you see that kind of moving through and if there'll be any marginal improvement on say a trade resolution. Thanks.
Mohan Maheswaran -- President and Chief Executive Officer
So the data center business, our customers tell us by mid-to-end of Q2, they expect to start -- the orders to start picking up again. They do see inventory there, but they expect that to come back and we know that there's still pretty big ambitions in terms of hyperscale data center build outs across the globe.
So we do expect that to be a -- predominantly a first half issue. Obviously, the trade issues give us a lot of concern, but because of China is a big opportunity for us, both from a demand standpoint, but also from the fact that they generate a lot of the -- from the build plans for our customers in other regions. And so it's just a -- lot of angst and about placing orders and things like that.
So any resolution for sure, we'll just free up -- clear up the uncertainty and help customers take more risk, I think which is important in this timeline.
Carlin Lynch -- B Riley -- Analyst
Okay, that's helpful. And if I could just ask a follow-up, you guys talked about a shifting mix shift -- a positive mix shift for you guys as margin. I was wondering, if you could touch on or give a little more clarity on what's driving that mix and where you guys see kind of margins moving throughout the year even as you know, have maybe a bit of a disappointing first quarter.
Emeka Chukwu -- Executive Vice President and Chief Financial Officer
So with regards to the mix, what we see is our data center revenue rebounding. In the second half, we see LoRa continuing to strengthen as we go through the year. We see more contribution to revenue from our video platform, so we see more contribution to revenue from our protection, industrial and automotive design wins. So clearly, we do see a lot of revenue growth going forward, coming from the higher gross margin end markets like industrial.
And that is why we do believe that we should expect to see gross margins stable. But also inching up nicely as we go through the year.
Carlin Lynch -- B Riley -- Analyst
Awesome. Thank you so much.
Operator
Your next question comes from the line of Harsh Kumar from Piper Jaffray. Your line is now open.
Harsh Kumar -- Piper Jaffray -- Analyst
Yeah, hey guys, thanks for letting me ask a question. Mohan, I had a simple question, if I was to take the $160 million you did in January and try to sort of bridge it up to the guide of, call it $130 million at the midpoint, how would you characterize that gap across your different kind of end-markets or product line. And then also you mentioned that business seems to have stabilized actually looking up very, very nicely in the last two weeks. In terms of ramp continuing through the rest of the year, how do you see the rest of the year? And previously, I think you guys have made a statement that fiscal '20 could be flattish, possibly went up, does that even -- does that still hold true. And then I've got a follow-up.
Mohan Maheswaran -- President and Chief Executive Officer
Let me start with that first, Harsh. I think it still does. I think it's going to be tight. But I think it's still potentially flat to slightly up, but depends a lot on the second half.The way we look at the year, currently as Q1 obviously is very soft, Q2 will start to improve and then we are expecting a stronger second half obviously and then by mix of business to kind of bridge to the, to the Q4 number.
Majority of our weakness is in our Signal Integrity Product area, a lot of weakness in data center, weakness in PON and base station also. Also China across all of our businesses is weak, there's no question about that. As I mentioned, POS is down significantly in China, so that has an impact on all of our businesses.
Frankly wireless -- our LoRa business is a significant business in China. China handsets also. And then also related to our SIP business. So we do expect, as that starts to get better, if China improves obviously that will be a positive for us. But that's, those are the main drivers of the weakness in Q1.
Harsh Kumar -- Piper Jaffray -- Analyst
Fair enough. And for my follow-up, Mohan, I wanted to ask about LoRa. I think you mentioned $100 million and $240 million (ph) for this year, which is a little bit off from your previous estimates. Now given that they were put out three or four years ago, we get that. Is that predominantly a function of what's going on in China and what you're seeing here and also is your additional $200 million of leads. Does that include tags or micro services in it or is that just bare chips.
Mohan Maheswaran -- President and Chief Executive Officer
Yeah, so the leads and opportunities are all related to chips including tags. Tags are chip-related product. So but not micro services that's a different -- of course different bucket for us. And then coming back to the range, it does, it is really significantly impacted by China softness. I mean, we -- we have been seeing a deterioration, I guess midway through Q4 in our China business overall.
And as I mentioned, the POS has come down significantly. So that has changed things. And that's one of the reasons I mentioned that the opportunity pipeline 70% of that is outside of China. So the LoRa balance. I think from a regional standpoint is going to shift nicely, but that's going to take a little bit of time.
Now, bear in mind, the $100 million to $140 million in FY '20, if we achieve the midpoint of that range would still be up, more will be up 56% or 54% something in that range, which is significant in the market environment we're in. So and as things improve through the year, I'll obviously keep you updated.
Harsh Kumar -- Piper Jaffray -- Analyst
Okay, thanks for the color, Mohan.
Operator
Your next question comes from the line of Mitch Steves from RBC Capital Markets. Your line is now open.
Mitch Steves -- RBC Capital Markets -- Analyst
Hey guys, thanks for taking my question. So I think the -- kind of the consumer and data center first half part make sense. But I guess the first one, I think that's kind of coming up, a lot in conversation is just how do you guys get comfortable in the back half of ramping up in terms of a year-over-year basis, if you're seeing, slowdowns particularly in China, especially if there's no resolution on the trade side, yet.
Mohan Maheswaran -- President and Chief Executive Officer
Yeah, it's a good question, Mitch. I think the China, we have to break it out into where we have business in China and that -- the China phenomenon is not really under our control. Not much, we can do. There is China softness in demand softness from the region itself. And then there's the uncertainty around all the geo situation.
I think the China demand uncertainty is really the, that the China demand situation is kind of the biggest piece of it at the moment. And we do expect that to start to see some improvements as PON gets deployed and base stations, more base stations get deployed and our customers are still telling us that they're planning to do that and so we don't see a change there.
Data center is the same, people -- our customers are still telling, talking about deploying lots of larger scale data centers. But there is inventory at the moment. So those give us indication that the second half is probably going to be stronger. How much stronger is a good big question, then if I look at the other businesses, smartphone, for example, we're starting to see little bit more positive kind of trends there.
And as I mentioned, the bookings over the last two weeks have strengthened. So that kind of supports some of that and then LoRa is going to continue to do very well. We've absolutely convinced that that we have a lot of opportunities, and the pipeline is shifting over plan. It's just about execution and transition and timing on that.
Mitch Steves -- RBC Capital Markets -- Analyst
Okay. Just a follow-up there. So I think the LoRa one make sense, essentially it's just the timing of what quarter comes in. But when I look at the two kind of bigger debate points in the semi space between smartphones versus data center. So of those two within your guidance of talking about call it flattish for 2020, which one are you guys more comfortable with in terms of growth. The smartphone side or the data center side?
Mohan Maheswaran -- President and Chief Executive Officer
Yes, I would say, it's more based on what happened in FY '19 and smartphones was not so strong in FY '19. I think that there's a good chance it will be stronger particularly if China and North America do better. But the smartphone business as you know is, it can be -- tricky. Now one of the things that's in our favor in smartphone is we have a little bit more content now, with not just protection, we have also proximity sensing. Data center, I do think though is that, it's an inventory issue. And that's why, once the inventory, I think works its way through in Q1 and maybe some in Q2, we'll start to see that pick up.
But at this point, I would say that probably smartphone is going to be little bit stronger and then data center depends on the second half.
Mitch Steves -- RBC Capital Markets -- Analyst
Okay, perfect. Thank you.
Operator
Your next question comes from the line of Quinn Bolton from Needham & Company. Your line is now open.
Quinn Bolton -- Needham & Company -- Analyst
Hi guys, first a clarification on the LoRa business, did you say in fiscal '19, that LoRa was probably 40% to 50% China-based and the China, but international or non-China was 70% of the design pipeline, just want make sure I got those numbers right.
Mohan Maheswaran -- President and Chief Executive Officer
Yes. In FY '19 that's our last fiscal year, Quinn, about 50% of the revenues, it's an approximation. But about 50% of the revenues was driven out of China. The opportunity pipeline, as we look at it 70% of that is outside driven by outside of China. A large part of that's in North America, but other regions outside China also.
And so as we see that -- those transition into -- into revenue, we should see a little bit more diversification in our geographical revenue balance of LoRa, which I think, the only reason I point that out and make a point of that is because China is very weak at the moment.
Quinn Bolton -- Needham & Company -- Analyst
And then a follow-up Mohan on the -- on LoRa. You gave us some very specific guidance for the number of networks, the number of countries, greater than 500,000 gateways greater than 140 million, cumulative end nodes, but the revenue range of $100 million to $140 million is fairly wide. If you hit those metrics on networks, countries, gateways, end nodes, does that kind of put you toward the middle of the $100 million to $140 million, does that get you to at the low end, does it get you to the high end, just some sense of, if you're tracking to the milestones you'd give us, does that kind of put you at the midpoint of the range or better or worse.
Mohan Maheswaran -- President and Chief Executive Officer
Yes, I would say, it's better. Quinn, if we hit the milestone, particularly the cumulative end nodes deployed. Gateways and networks and countries doesn't necessarily translate to revenue. It's the conversion of the opportunities into real deployments that translates into revenues, because of the end nodes are really what drives the revenues. So I would say the cumulative end nodes though if we hit 140 million, I think it will take us closer to the high-end and the midpoint.
Quinn Bolton -- Needham & Company -- Analyst
Perfect. And then just lastly, I know, we had obviously (ph) last week, you guys were in your quiet periods, you're -- probably didn't get a chance to see a lot of investors, any particular highlights do you want to share with us, whether it's Tri-Edge or just other products in the optical space?
Mohan Maheswaran -- President and Chief Executive Officer
Well just really a clarity around our strategy and confirmation that I think we have a very good strategy and execution is key, most of our customers recognize the value of our current ClearEdge family and that continues to do well despite the current short-term issues with data center inventory and things like that. And then as we look forward, I think the consistent theme is high performance, but at the lowest power and lowest cost and we're having a Tri-Edge family out there. Now being able to talk to customers as we are sampling for both 200 gig modules -- short reach modules, eventually longer reach modules and then eventually combined with other platforms to provide really a roadmap for our customers. I think is very good for the PAM4 plans. And then the FiberEdge family, which as you know, supports DSP partners, I think is a really good platform and it's starting to get design wins also. So in general, we found it a very good show. It's just confirmation of our strategy, and I think we feel good about it. Plus, then you add on to that the growth of 10 gig PON and the direction that PON is going in, which is more higher bandwidth, which is also good for us. And then the base station side as well. Again confirmation that high speed links for fronthaul and backhaul, which will need CDR functionality I think is also confirmation. So more of the same. I think also talking to the customers about China and the weakness I think confirmation there that the first half is going to be weak in general.
Quinn Bolton -- Needham & Company -- Analyst
Great. Thank you for that color, Mohan.

Your next question comes from the line of Tore Sandberg. Your line is now open.
Tore Sandberg -- Stifel -- Analyst
Yes, thank you. Just a few follow-ups. First of all, Mohan. As we think about the data center recovery in the second half, how much, I know it's hard to quantify that? How much of that is kind of the market coming back versus some of these new programs? And I'm thinking, especially the PAM4 CDRs for 200-gigabit and 400-gigabit becasue my sense is that's probably more of a fiscal '21 event, but just want to understand sort of (multiple speakers)
Mohan Maheswaran -- President and Chief Executive Officer
Yes, that's correct.
Tore Sandberg -- Stifel -- Analyst
How much is going to be market?
Mohan Maheswaran -- President and Chief Executive Officer
Yes, that's correct, Tore. Most of the PAM4 stuff is going to be latter part of this year and into next year. So it's all -- it's all market-driven. It's all inventories being used up and some of the hyperscale stuff continuing to build out, and it's pretty global statement, I think on data centers. I think we've seen China started to pick up but again with the China softness that's as muted. But I do think that it's more driven by market dynamics, I don't think it's specific to PAM4.
Tore Sandberg -- Stifel -- Analyst
Okay, very good. And you sound pretty upbeat on more operators globally on LoRa, any sort of anecdotes that you can share with us there as far as because I am obviously thinking about the comparison that are always made right between NB IoT and LoRa and some of the other WAN technologies out there. So I don't know, if there's anything you can share with us as far as anecdotes you've had with or conversations you've had with operators that really want to more -- do more meaningfully with LoRa.
Mohan Maheswaran -- President and Chief Executive Officer
Yeah, I think and I kind of alluded to some of those on my prepared remarks, but Orange's win with Veolia is a significant milestone for an operator, very significant actually over a 10-year period. So that's one. And then I say, I made some comments on some new use cases, Comcast with machineQ's Victor rat trap or rodent trap connectivity, that one is a very interesting use case, that I think has a global application, obviously the Amazon Ring discussion on their smart lighting. These are use cases that are really going to drive more demand for some of the operators and Tata is another one where winning a gas metering LoRaWAN use case in India, it kind of paves the way for them to then win many more similar types of use case wins over this gas metering or water metering or whatever, and that's great for the operators.
The operators that have joined the LoRa Alliance and have built out LoRaWAN networks have obviously taken risks. They built out network or put their name behind it and are now looking for use cases and real demand, and so that's really key for us and that's one of the reasons why I put emphasis on the LoRa cloud service, because it's very unique. This is not something many companies can do, and I don't think it's going to be something that you'll see for many chip companies, it's a very unique capability that we are able to bring and add value to our partners, including operators, who want to provide a highly accurate services with the complement between power and accuracy for Geolocation, for tracking of assets and provide that service to customers. So lot to be done still and lot to prove. But I think it's a real milestone for us.
Tore Sandberg -- Stifel -- Analyst
That's really helpful. Just, one last one for Emeka. Then I'll go away. So Emeka, you said inventory days obviously will be up in the quarter. Will it still stay within that 90 to 100 range or do you think you'll probably get, go a bit beyond that.
Emeka Chukwu -- Executive Vice President and Chief Financial Officer
It might go slightly ahead of the 90 to 100 days. But for the most part, we do expect to manage inventory within those levels.
Tore Sandberg -- Stifel -- Analyst
Very good. Thank you.
Operator
Next question comes from the line of Harsh Kumar. Your line is now open.
Harsh Kumar -- Piper Jaffray -- Analyst
Yes, hey, thanks for letting me ask a follow-up. Mohan and Emeka, I was looking at my model and I'm trying to figure out, I know you guys don't guide more than one quarter. But I'm going back to your comment about being flattish or possibly -- possibly even flat to slightly up. So at some point in time, I have to build in kind of a hockey stick ramp upward.
Do you think that starts to happen with fiscal 2Q or do you think that's mostly a second-half phenomenon.
Mohan Maheswaran -- President and Chief Executive Officer
Well, I'll start and then Emeka can finish actually, he won't say. I mean, Q2, we're expecting to come back, Harsh, in Q2, but realistically, you -- we've been in the semi space for a long time, when you have one down quarter, you normally find that the second quarter may come back a little bit. But it doesn't necessarily come back as a hockey stick.
But if it comes back, which I do think it will, then I think it paves the way for a much stronger second half. So we'll see, I don't know how strong the second half is going to be. But we have enough growth drivers going on, and enough unique things going on in the Company that I think that we should be able to outperform.
Harsh Kumar -- Piper Jaffray -- Analyst
Thank you.
Operator
There are no further questions at this time, please continue presenters.
Mohan Maheswaran -- President and Chief Executive Officer
Okay, in closing, fiscal year 2019 was an exciting year for Semtech, as we delivered a record financial performance. While we are seeing a very slow start to fiscal year '20, we believe the strength of the secular drivers behind our growth engines are clearly intact and expect a stronger second half that should contribute to what we expect to be another solid year.
With that, we appreciate your continued support of Semtech and look forward to updating you all next quarter. Thank you.
