SITM

Sitime Corporation

A maker of silicon-based timing chips that replace the quartz crystals found inside nearly every electronic device, keeping clocks and signals in sync across AI data centers, phones, cars, and industrial gear. Founded in 2005 in Santa Clara by researchers Markus Lutz and Aaron Partridge, it builds its oscillators and clock chips from microscopic moving parts etched into silicon, outsourcing manufacturing to foundries like Bosch and TSMC. The name blends "silicon" with "time," and its MEMS timing technology—grown out of work on tiny silicon machines—aims to make electronics more reliable than fragile quartz.
