MEMS Clock Generators

Cascade Platform MEMS-based Clock Generator Package

MEMS Clock Generators

SiTime MEMS-based clock generators feature up to 4 independent Frac-N PLLs, wide frequency range, low jitter and a rich set of programmable features. By integrating the MEMS resonator, the need for a quartz crystal time reference is eliminated, along with all performance, design, quality and reliability issues associated with traditional quartz-based devices.

  • Up to 50% less board space
  • Always-accurate clock synthesis by eliminating crystal capacitive mismatch
  • Always-reliable startup even at cold temperature and in other harsh environmental conditions
  • No jitter degradation because of noise coupling onto a crystal interface
  • No activity dips/frequency jumps inherent with quartz
  • 10x more resistant to vibration and board bending
