SiTime's programmable clock generators are the first in the industry to integrate MEMS resonators, thus eliminating the need for external crystals and other clock sources.

Key features of SiTime's programmable clock generators include:


  • Small SOT23-5 package best for board level solder joint reliability
  • Wide frequency range from 1-137MHz
  • Best stability of ±20 PPM from -55 ºC to 125 ºC


Refer to the Automotive section for AEC-Q100 compliant clock generators (SiT2024, SiT2025)
