Revolutionizing The Timing Market

Why Use MEMS?

Quartz Crystals Versus MEMS

SiTime is a crew of passionate and persistent innovators who took on the goliath in timing. For decades, quartz dominated the industry, and we decided to change that. There purpose was clear: To build the highest performing and most reliable timing devices, smaller than a pinhead.

SiTime’s already owns 90% of the MEMS timing market, and given all the barriers they've broken, it’s only a matter of time before they make quartz obsolete.
