The world's most popular micro-electro-mechanical system (MEMS) oscillators just got a boost in stability by SiTime's TempFlat technology which extends its reach into the parts-per-billion timing chip market for base stations, small cells, and optical networking: R. Colin Johnson @NextGenLog
Quartz crystals today vary their frequency by temperature as much as 200 parts-per-million (ppm), but TempFlat MEMS technology varies by as little as 20 ppm. Further Reading
