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

Everyone expects the best from technology. Being connected and having access to information are taken for granted. But did you know that connectivity relies heavily on timing?

If timing fails

  • Battery life would be much shorter
  • Internet browsing would be slow or stop completely
  • Calls, emails, and text messages wouldn't be sent

SiTime devices ensure reliable connectivity in cell phones, tablets, smartwatches, and fitness tracking bands. Plus, our timing solutions use up to 40% less power than quartz, which means batteries can run longer.

SiTime’sMEMS时机解决方案提供一个独特的combinµ力量ation 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 availablein 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
  • Ultra-short lead times
