A small part from SiTime runs a big part of your world

Being connected and having access to information are taken for granted. But did you know that connectivity relies heavily on timing?

If timing fails

  • Internet connectivity will be slow or stop completely
  • Calls, emails, and text messages wouldn't be sent
  • Your portable medical device may not send information to your doctor
  • You won't be able to control your home's security system, lights, garage door, or anything that runs on your smartphone

SiTime devices ensure reliable connectivity in mobile and IoT devices. Plus, our timing solutions consume less space and power, making products smaller and running longer.

Features & Benefits

What are customers saying?

“Garmin makes products that are engineered on the inside for life on the outside. Our innovation focuses on developing technologies that enable our customers to enrich their experiences as they pursue their passions. SiTime’s MEMS timing solutions help extend battery life across several of our product lines.”

Patrick Desbois
Executive vice president of operations

SiTime’s µPower MEMS timing solutions offer a unique combination of ultra-small footprint, low power operation, and accuracy, making them ideal for clocking space-sensitive, battery-driven products. With programmable drive strength, these devices can drive multiple loads, such as the BLE sleep clock, RTC, audio, and other connectivity SOCs. Plus, they are available in custom and low frequencies that quartz cannot support.

  • Programmable frequency from 1 Hz to 26 MHz
  • Small footprint, 1.5x0.8 mm CSP (1.2mm2) or 2.0x1.2 mm QFN
  • Oscillator output drives multiple loads and eliminates XTALs
  • Ultra-low power, as low as <1 µA
  • NanoDrive™ programmable output swing lowers power
  • Stability as good as ±3 ppm improves timekeeping and system power
  • Robust performance and higher stability in harsh environments
  • New EpiSeal resonators, impervious to small-molecule gases
  • Short lead times
