Spacecraft Timing Architecture: Microchip’s Radiation-Tolerant, Low-Power, Low-Jitter Six-Output Clock Generator
Spacecraft timing systems must provide highly stable, precise signals for navigation, communications, and scientific instruments, even when GNSS signals are weak or unavailable. Designers often rely on multiple oscillators and buffers to supply precise frequencies to various subsystems, adding size, mass, and complexity. Microchip Technology announces the space-grade DSA504RT, a radiation-tolerant, six-output programmable clock generator for addressing the complex timing needs of aerospace and defense applications.
The DSA504RT streamlines timing architecture by generating multiple clean, phase-aligned frequencies from a single master source. Additionally, this solution reduces the need for multiple discrete oscillators, lowers overall component count, and improves system failure in time (FIT) rate. It also reduces power consumption and mass, as well as simplifies distribution networks to keep all subsystems synchronized even in the harshest environments and during GNSS outages or disruptions.
Analog Phase-Locked Loop (APLL) features spread spectrum capability, two fractional and two integer dividers, and six highly configurable output buffers, each of which can be configured as a differential driver (LVPECL, LVDS, or HCSL) or as a pair of single-ended CMOS outputs. The DSA504RT delivers ultra-low jitter performance as low as 200 femtoseconds (12kHz–20MHz) and is compliant with PCIe Gen 1-7 standards. This level of integration allows engineers to replace multiple crystals, oscillators, and buffers with a single device, improving design reliability, reducing Bill of Materials cost, and design complexity.
“This Microchip clock generation device is a game-changer for space applications. It can offer a comprehensive clock tree solution, producing three different clock families and up to six different frequencies, each buffered on a variety of selectable output drive types,” said Maamoun Abou Seido, appointed vice president of Microchip’s timing communications group. “Replacing numerous oscillators, buffers, and synthesizers, the DSA504RT saves board space and reduces part count to improve the system’s Failures in Time (FIT) rate in these high-reliability applications.”
The DSA504RT, offered in QFN28 and CQFP32 packages, serves as a companion device for complex aerospace and defense systems. It enables high integration of clock architectures within a single chip, distributing precise timing references to subsystems built around radiation-tolerant or radiation-hardened FPGAs and MCUs.

DIY hardware quantum RNG wired into a Magic 8-Ball
| I wanted a "real" quantum random number generator, something where every bit is an actual physical quantum event. First attempt was a 1970s Canon FD 55mm f1.2 with a thoriated rear element. It's pretty radioactive (the Geiger counter make scary noises). But radioactive decay gives you when an atom popped, which is timing-random, not the which-path coin flip I was after. The build that actually worked is optical: attenuate a light source down to single photons, fire them at a 50:50 UV beam splitter, and read which way each photon went with two detectors. Through → bit 0. Bounce → bit 1. The detectors are two Hamamatsu PMT modules a friend gave me, pulled out of a dead lab instrument. I tore it down, yanked the dichroic mirror, and dropped in a UV 50:50 splitter. For a fluorescent source I ended up using 3D-printer filament — it's faintly fluorescent at the right wavelength and doubles as a light-tight cover. All the detection and conditioning runs on a Red Pitaya (FPGA + fast ADCs):
The hard part genuinely wasn't generating random-looking bits, but it was proving they were real random bits from the optical system and not other noise sources. Most of the project ended up being diagnostics... Payoff demo is a Quantum Magic 8-Ball: hit a button, it pulls fresh quantum bits and gives you one answer (and, if you're an Everettian, every other answer somewhere in the multiverse). Full build log with schematics, scope shots, and the FPGA stuff: https://dnhkng.github.io/posts/building-the-beam-universe-splitter/ Happy to answer questions on the analog front end or the FPGA fabric — the analog side is honestly my weakest area, so I'd welcome the critique.

I made a 1kW lab bench power supply from scratch
| Hello r/electronics, In this post, I want to share my project that I’ve been working on in the past few months. It’s a custom-built lab bench power supply. Such a project is common in the DIY community, so what makes this one different? The custom-designed SMPS board that I engineered from scratch isn’t your typical “let’s put this power supply module into a case” approach. So let’s dive into the working principles, design decisions, and in-depth test results. The Forwarder 1kW is the SMPS board that I designed and used in this project. It’s based on a hard-switch, half bridge topology. The full features of this power supply are as follow:
The working principle of this design is about as simple as it can get for a switched-mode power supply. I talked about the working principle of my design over on r/AskElectronics, so I’m not going to repeat it here. Most of the concepts stay the same, just with some design adjustments and the numbers changed. https://www.reddit.com/r/AskElectronics/comments/1s8ll9g/ Now, I want to go in detail about the design decisions that led into this design that you may find interesting.
After I finished the board, I wanted to know how my design performs in real-life. So, I conducted a few tests that are relevant for a power supply. The testing rig was pretty simple:
The test conducted, along with their results are as follow:
I’m here not to glaze over my design. After reviewing the results and doing a retrospective, here are my critical opinions about this design. What I like about this design:
What I don’t like about this design:
The full schematic, gerber files, KiCAD save files, spreadsheet calculation, and full-res images are available on my Github repository: https://github.com/Luq1308/Forwarder1kW The build process and the in-depth testing are available in my YouTube video: https://youtu.be/MGMqqtXgwRg That’s all I have about this project. I hope this post is informative and can be used as a reference or for benchmarking purposes, in which I had difficulty in researching previously. If you have any unanswered questions, let me know and I’ll try to answer them. Thank you for reading, and I'll see you next time. [link] [comments] |
Google’s Pixel 10: Upgrading smartphones again
Just because generational device improvements aren’t in-your-face obvious doesn’t mean they aren’t sooner-or-later still tangibly impactful.
As mentioned last week, one of the perks that accompanied my recent personal-cellular-line transition from AT&T to Google Fi Wireless was a free (after two years’ service, albeit still notably discounted upfront) Pixel 10 smartphone, which I’d needed to press into service immediately in order to qualify for the various promotion discounts (this “stock” photo is of the “Indigo” colorway; as noted last week, mine’s “Obsidian”):
![]()
As long-time readers may recall, I’ve been a (mostly) Google Pixel “daily driver” since mid-2017, across multiple product generations. And I’ve been specifically using a pair of Pixel 7s for the past three years. So, I feel a “bit” qualified to offer some observations and comparisons with past device experiences. Without further ado…
I’m not a power userWhat I’m referencing by means of this admittedly cryptic initial section header is the fact that although the Pixel 10, which I initially wrote about as part of my coverage of Google’s August 2025 multi-product launch event, has a three-generation-newer Tensor SoC inside it (the G5, versus the earlier G2), the performance differences aren’t strikingly obvious. at least to me. Not that they’re nonexistent, mind you; Google’s increasingly impressive AI “chops” are most evident at the moment in the handset’s computational photography capabilities. That said, I strongly suspect that AI’s effects will be comparatively even more broadly visible (both in their results, responsiveness and fundamental existence) with the passage of time.
To that point, the “bump” in RAM from the Pixel 7 (8 GBytes) to the Pixel 10 (12 GBytes) is likely at least as important as is bolstered inference processing “muscle” in delivering local AI enhancements, as it enables on-device deep learning models to be more comprehensive and otherwise robust than would otherwise be the case, delaying if not completely foregoing a performance- and power-sapping handoff to the “cloud” in the process. And if there’s one upside to today’s semiconductor memory shortages, it’s that it’ll compel Google’s and other organizations’ developers to make their models even more efficient (while retaining sufficiently high results accuracy) than might otherwise be the case.
Pleasantly pocketable and reliably chargeablePut the two phones side-by-side and you’ll realize that although the active screen dimensions and other high-level display attributes are identical (6.3” diagonal OLED with 1080 x 2400 pixel resolution, though the Pixel 10 variable refresh rate tops out at 120 Hz versus 90 Hz for the Pixel 7, for whatever that’s worth…), the Pixel 10 (at left in the following photos) is actually a smidge shorter and narrower, the result in part of bezel decreases, not to mention rounder:
- Pixel 7: 6.13 x 2.88 x 0.34 inches (155.6 x 73.2 x 8.7 mm)
- Pixel 10: 6.02 x 2.83 x 0.3 inches (152.8 x 72.0 x 8.6 mm)


That aside, the Pixel 10 has a higher internal battery capacity than its Pixel 7 forebear—4,970 mAh vs 4,355 mAh—and the foundry transition from Samsung to TSMC that accompanied the to-Tensor G5 SoC evolution also aspires to improve not only performance (decreasing the energy consumption necessary to complete a given task in the process) but also stored-electron efficiency, with the two factors combining to boost claimed battery life.
Speaking of battery life, a few words on charging. The Pixel 7 supports wired charging at up to a 21W incoming power payload and wireless charging at up to 12W with conventional Qi chargers or 20W with the pricey, seemingly no longer available 2nd-generation official Google Pixel Stand:

For the Pixel 10 family, there’s a new wireless charger, the magnet-augmented Pixelsnap (reflective of the magnet-inclusive and Apple MagSafe-reminiscent QI2 support now within the phones themselves), which supports 15W charging speeds with the baseline Pixel 10 and 25W for the high-end Pixel 10 Pro (both of which also support wired charging at 30W rates):
And even though, as with the Pixel 7, I still need to use a case that’s magnet-inclusive with the Pixel 10 to ensure sufficient “cling” strength to a charger or whatever else I’m striving to stick it to (or, depending on the circumstance, stick to it), MagSafe-tailored chargers now work with it, too. With the Pixel 7, charging reliability with magnet-based chargers such as my Belkin-based desktop:

and in-car setups:

was flaky at best, typically DOA with the magnet-augmented case but magnet-less foundation. Now, for whatever reason, it’s ironclad (I hope I haven’t jinxed myself by writing those words).
Optics upgradesSpeaking of computational photography, while the Pixel 7’s front camera did implement face recognition-based unlock support (for the first time since the Pixel 4), it was both too flaky and insufficiently robust in associated software support to be something I could rely on. Beginning with the Pixel 8 (therefore also including the Pixel 10), the implementation is not only faster but also more accurate and broadly robust, thanks to machine learning algorithm augmentation:
That said, it’s still reliant on the front visible light image sensor, dropping the Pixel 4’s Kinect-reminiscent and IR-derived structured light approach in the process, in an ironic contrast to the conceptually similar IR-based TrueDepth technique that Apple uses to this day with FaceID. As such, it doesn’t work great in dim light, and not at all in the dark; thankfully, Google has also seemingly improved its historically woeful fingerprint ID detection implementation as a backup in such situations. And there’s always also your PIN or other unlock sequence, after all…
One other camera-related note; in the earlier backs-of-phones images you might have noticed what appeared to be a third lens on the Pixel 10’s rear “camera bar”. Or maybe you’ve just noticed the increased prevalence of ultra-closeup pictures in my recent teardowns, ones specifically taken without the bulky multi-piece accessory I had to use previously:


Google refers to it as a 5X telephoto, and it’s admittedly nice for that, but its Macro Focus capabilities are what I’m lovin’ the most, right now at least.
Tying up loose endsI mentioned earlier in this piece, and have also mentioned previously, how much I appreciated the fact that Google extended support (not only security patches but also full O/S updates) for the Pixel 6 and 7 series from 3 to 5 years at the end of 2024. As such, they’ll remain reliable backup-at-least options in my smartphone arsenal for at least the next year-plus. That said, beginning with the Pixel 8 series, therefore also including both my Pixel 10 and Pixel 9a, support was further extended to seven years from initial release date. Nice.
One (very) minor downside, for which I have nobody but myself to “blame” since I knew about it before I pressed “purchase”, involves ultrawideband (UWB) support. Apple’s latest-generation AirTag trackers leverage not only integrated Bluetooth and Wi-Fi subsystems but also UWB capabilities to enable more precise location discernment. So too do advanced Android-friendly trackers such as Motorola’s Moto Tags, one of which currently resides on my teardown shelf:

This is all well and good, but there’s one key qualifier: tracker-based UWB is only meaningful if the connected device that’s doing the tracking also supports UWB. That gives a green light to the Pixel 10 Pro, but not my UBW-deficient Pixel 10. Oh well…First World problems strike again.
And speaking of Android friendliness, I’m ironically writing this piece one day ahead of Google I/O 2026, with my special-project coverage of it scheduled to be published weeks ahead of this piece. Google has already talked some about Android-centric stuff at least week’s (again, as I write this) Android Show I/O Edition, replicating a cadence tradition it did for the first time a year ago. I’ll be curious to see what else Android- and Pixel-related is unveiled tomorrow. And I hope it doesn’t obsolete what I’ve just written today in the process! I’ll see you all “on the other side”, where I as-always also welcome your thoughts in the comments.

Nearly done making DIY Remote as a soldering kit
| I'm designing a DIY remote intended as a soldering kit. My design requirements were:
First I had to think about power management, microcontroller and RF module. I'll start with the RF module first... I chose the popular nRF24L01, although the version I am using has a can on it and has FCC/IC. I prefer this version over the generic one that is everywhere. Works well and has a ton of support! The range it can achieve is also more than sufficient for the intended applications. Since this RF module does not officially support 5V (Yes, I contacted the manufacturer .. there are some versions of the nRF24L01 that *do* support 5V, but this module does not), I had to stick with 3.3V. As my first design goal was to use as few parts as possible, I did not want to use a logic level shifter (LLS). So I needed a microcontroller that operates on 3.3V. Like the Pro Mini, but in my case a Nano form factor running on 3.3V (I had to drop the clock frequency a bit to remain within manufacturer suggested conditions). Even at reduced clock speed, the ATmega328 running at 8MHz and the nRF2401 module combined are still quite fast... at least for the human mind. (more on that below) Both the RF module and the microcontroller can operate well at 3V, so I figured I just use two AA batteries. Then I only need some filters but no other real power management components like a linear regulator. Perfect for what I was trying to design. Also, I wanted to pick batteries that are super common, cheap enough and can be recharged. I made a 3D printed base for this remote as well and it now hold very well. I used the remote as a general HID controller for a couple custom games I made and it works great. Response time is super (no lag or delay that is noticeable) and the battery lasts more than a day. All the parts are THT (through-hole) and therefore easy to solder together (second design goal). I mounted the RF module and the microcontroller using female headers. They are secure enough but this allows them to be removed easily and used in other projects. This was my third design goal. I am working on a remote car and drone (under 250g), both of which can also be controlled with this remote. So there are quite some applications. [link] [comments] |
How AI is driving a new paradigm in test distribution

Artificial intelligence (AI) is accelerating semiconductor innovation at a pace that is forcing a rethinking of conventional production test strategies. The rapid scaling of graphics processing units (GPUs), AI accelerators, and heterogeneous compute architectures is increasing not only device complexity, but also the amount of test content required to validate performance, reliability, and quality across the manufacturing flow.
As AI infrastructure investments continue to expand, semiconductor manufacturers are building increasingly sophisticated devices that combine massive transistor counts, advanced packaging, high-bandwidth memory (HBM), chiplet architectures, and emerging co-packaged optical (CPO) interfaces. These devices are redefining the relationship between design, validation, and production test.
The result is a new test paradigm in which test content, infrastructure, and analytics are distributed dynamically across multiple insertions—from wafer sort through system-level test (SLT)—to balance cost-of-test, defective-parts-per-million (DPPM), and time-to-market objectives.
AI devices driving a step change in test requirements
The transition from monolithic devices to heterogeneous multi-die systems has substantially increased the burden on automated test equipment (ATE). AI processors now incorporate far more compute engines, memory bandwidth, and power-delivery complexity than previous generations of high-performance devices.
At the same time, traditional transistor scaling no longer delivers the same gains once associated with Moore’s Law. To continue improving system performance, designers are adopting More-than-Moore integration strategies that combine chiplets, 3D packaging, integrated voltage regulation, and advanced interconnect technologies within increasingly dense package architectures. These changes are producing several cascading effects on tests.
First, scan and functional test workloads are growing dramatically as transistor counts increase. Modern AI devices require extremely large volumes of scan vectors that must be delivered at gigabit-per-second speeds through either massively parallel digital channels or high-speed serial interfaces such as PCIe and USB.
Second, power requirements are rising rapidly. Device power supplies must now support kiloamp-class current delivery while maintaining tight regulation and accuracy under highly dynamic loading conditions. Flexible power architectures capable of extensive channel ganging are becoming increasingly important as final-test power envelopes continue to climb.
Thermal management is becoming equally critical. AI devices entering production are expected to push package-level power dissipation into multi-kilowatt ranges, making active thermal control essential throughout the test flow. In advanced environments, thermal systems are increasingly paired with predictive analytics capable of anticipating thermal excursions before they occur, enabling proactive cooling and tighter junction-temperature management.
Advanced packaging complicates multisite test
Migration toward larger 2.5D and 3D packages is also changing the physical realities of production test. As package sizes expand to accommodate more chiplets, HBM stacks and photonic components, device handling and multisite efficiency become more difficult to optimize. Larger sockets consume increasing amounts of device-under-test (DUT) board real estate, constraining routing resources and limiting tester scalability.
In parallel, manufacturers are moving toward larger tray formats carrying fewer devices per tray because of package dimensions and handling constraints. These shifts reduce some of the traditional efficiencies associated with high-parallelism production environments.
The addition of photonic and CPO technologies introduces another layer of complexity. Optical interfaces require integrated electro-optical validation across multiple stages of manufacturing, extending test coverage well beyond conventional electrical characterization. As a result, optical instrumentation is increasingly being introduced at wafer probe, optical-engine test, final package test, and SLT insertions.
Test engineering becoming more software- and data-centric
The growing complexity of AI devices is changing not only hardware requirements, but also the nature of test engineering itself. In other words, engineering organizations are under pressure to accelerate bring-up, reduce debug cycles, and maintain quality targets despite rapidly increasing test content volumes. This is driving tighter integration between design, silicon validation, and manufacturing teams.
As a result, AI-assisted software tools are beginning to play a larger role in test-program generation, debug optimization, and adaptive workflow management. Real-time analytics platforms can now aggregate data across multiple insertions, enabling faster correlation of failures and more intelligent allocation of test coverage throughout the production flow.
In these environments, test content is no longer statically assigned to a single insertion. Instead, coverage increasingly shifts throughout the flow depending on where defects can be detected most efficiently and economically. This distributed approach to test is becoming essential as AI devices scale toward trillion-transistor complexity.
Shifting test left reduces packaging risk
One major trend is the movement of more test content earlier in the manufacturing flow. For advanced AI devices, packaging costs now represent a substantial portion of total product cost because of technologies such as HBM and chip-on-wafer-on-substrate (CoWoS) integration. Packaging defective die into expensive multi-die assemblies can significantly increase material waste and reduce yield.
To mitigate this risk, manufacturers are pushing more coverage to wafer-level and die-level test insertions to improve known-good-die confidence before assembly. Figure 1 illustrates how test distribution increasingly spans the entire workflow, with tighter interaction between design, validation, and production environments.

This shift-left strategy (Figure 2) includes broader scan coverage and expanded fault modeling at speed testing, and increasingly system-aware functional validation at the die level. Some workflows also incorporate calibration, trimming, and memory repair operations prior to package assembly.

In more advanced implementations, active thermal control capabilities are also migrating closer to singulated-die test stages. The objective is straightforward: identify marginal or defective components before they enter expensive advanced-packaging flows.
System-level test expanding
At the same time, other forms of coverage are shifting later in the process. As devices become more heterogeneous and application-specific, certain failure mechanisms emerge only under realistic operating conditions involving software execution, thermal loading, timing interactions, or high-bandwidth traffic patterns.
These conditions are often difficult—or impossible—to replicate during traditional structural or functional test insertions. Consequently, SLT is becoming increasingly important for AI and HPC devices. System-level environments can expose defects associated with workload execution, protocol interactions, and real-world operating states that are not observable during earlier production stages.
New approaches, including scan-over-PCIe methodologies and highly parallel SLT architectures, are helping manufacturers improve coverage while attempting to control the significant test times associated with these environments. Figure 3 illustrates the corresponding shift-right strategy.

Real-time analytics enabling adaptive test distribution
The increasing fragmentation of test insertions is creating demand for tighter orchestration across the production floor. Modern test infrastructures are evolving toward highly connected environments in which data streams continuously between validation, wafer sort, final test, and SLT operations. Real-time analytics platforms can then use this data to optimize insertion decisions, adapt test limits, and improve yield-learning cycles.
GPU-accelerated edge inferencing and AI-based decision engines are also enabling faster adaptive responses during production. In some cases, computation can be offloaded from the tester itself to remote compute infrastructure, allowing more sophisticated analytics without compromising throughput.
This level of coordination requires consistent software frameworks and portable test content capable of moving seamlessly between insertions and platforms. So, shared execution environments and unified debug tools are becoming increasingly important as manufacturers attempt to reduce engineering overhead while accelerating deployment.
Optical test adds new workflow stages
CPO and photonic integration introduce additional challenges because optical functionality must be validated alongside traditional electronic behavior. Unlike conventional semiconductor devices, photonic systems often require multiple dedicated insertion points throughout manufacturing. These may include photonic wafer test, dual-sided probing of electronic and photonic die, optical-engine characterization, and additional packaged-module validation after integration with ASICs.
As with electrical tests, much of this optical validation is shifting earlier in the flow to ensure known-good optical engines prior to final assembly. However, full electro-optical verification often still requires additional socketed final-test and SLT insertions after system integration.
Figure 4 highlights how optical test introduces additional insertion points spanning photonic wafer test, optical-engine validation, final package test, and SLT.

Test distribution is becoming a strategic optimization problem
AI is transforming semiconductor tests from a relatively linear production step into a highly distributed optimization challenge involving power, thermal management, data analytics, packaging economics, and workflow orchestration. Meeting future quality and throughput requirements will require closer collaboration across the semiconductor ecosystem, including design teams, ATE suppliers, packaging providers, and system integrators.
As AI devices continue scaling in complexity, test infrastructure must evolve from traditional defect screening toward intelligent, adaptive validation environments capable of making real-time decisions across the manufacturing flow. In that sense, the future of semiconductor test may depend as much on data movement and workflow intelligence as on the tester hardware itself.
