STI offered this ability back in 2007. We tried it on Ethernet devices (15MHz) as a crystal replacement and it worked fine. Plus the drift over the expected lifetime was better than quartz. It was cost that was the hold-up.
Accuracy is not yet specified since actual production devices are not yet announced, but in testing IDT claims drift is just 2 PPM for pMEMS compared with 10 PPM for quartz after 1400 hours at 125 degrees C.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
