SiTime offers a complete portfolio of MEMS MHz oscillators. These devices offer configurable features not available with quartz and are designed for higher reliability, shorter lead times, and solving unique timing problems, such as EMI and in-system programmability. They can replace quartz oscillators without any redesign or board layout changes.
SiTime offers a one-stop shop for all differential oscillators requirements, down to 70 fs RMS jitter. These high-performance oscillators are ideal for optical modules, networking, server, storage, and telecom applications and offer low jitter, as well as excellent immunity to power supply noise (PSNR) and environmental hazards such as shock, vibration, and EMI.
