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

Since technology plays a huge role in our daily lives, networking and telecom infrastructure across the world needs to be in sync 24/7.

If timing fails

  • You experience dropped calls and slow web browsing on your phone
  • You see fuzzy images while watching TV
  • Stock trades fall through

SiTime helps make this synchronization possible. We’ve designed our MEMS timing solutions to deliver the performance and reliability that keeps network infrastructure running. Our timing solutions deliver the best dynamic performance in the face of environmental disturbers, such as shock, vibration, high temperature, electromagnetic interference, and air flow.

Best dynamic performance
Frequency slope (ΔF/ΔT): 1 ppb/°C, 10°C/min ramp
Vibration immunity: 0.1 ppb/g
ADEV: 3e-11, 10s averaging time
PSNR: 0.2 ps/mV
30x more reliable
FIT rate: <2, MTBF: 1.2 billion hours
