In light of today’s great podcast with Megachips, I decided to revisit SiTime. For those who may not be aware Megachips own approximately 25% of SiTime (as at Feb 2022). I know they have been discussed a while ago and @FactFinder amongst others posted about them but I was particularly interested in this extract from the 15th of March. I’m not saying they are using AKIDA, I’m just saying they are aware of the need for Edge devices. I would imagine Megachips would have communicated the advantages of AKIDA to the other companies they own/part own. This is from their webpage:
"Twenty-two million autonomous vehicles on the road by 2025, the rapid adoption of 5G, and the continued growth of data centers will require a large buildout in outdoor, decentralized edge networks,” said Piyush Sevalia, executive vice president of marketing at SiTime. “These new edge devices and their precision timing heartbeat must perform reliably in the presence of extreme temperatures, thermal shock, and vibration. Here, our Elite X Super-TCXO shines by delivering 2x better stability and 30x higher reliability than quartz. Consequently, we believe that Elite X will now be the precision timing device of choice in edge equipment.”
To enable new time-sensitive services such as ADAS, virtual reality, and smart manufacturing, edge devices will need to deliver faster speeds with lower latency. Precision timing plays a crucial role in their success. Legacy timing devices such as quartz TCXOs and mini-OCXOs have well-known weaknesses such as sensitivity to thermal shock and vibration, stability degradation at high temperatures, and shorter operating life. By using silicon MEMS technology that is inherently more robust and reliable, Elite X overcomes these problems and enables the next generation of time-sensitive services everywhere.
In edge networks, additional specifications such as aging, warm-up time, and power consumption are important for overall performance. Even here, SiTime Elite X outperforms legacy timing devices, simplifies system design, and offers dependable, consistent performance.
Their new Elite X Super TCXO SiT5501 uses 4 x lower power. Samples of the SiT5501 Elite X Super-TCXO are available now, with volume production in Q3’2022.
