Network Synchronizers

SiTime network synchronizers feature 4 independent time domains, programmable loop bandwidth, DCO mode with 0.001-ppt resolution to frequency, and phase recovery from syncE and IEEE 1588, best-in-class lock time and hitless switching performance. These devices come with 4 fractional PLLs, flexible input to output frequency translation, wide frequency range from 0.5 Hz to 2.94912 GHz, and a rich set of programmable features in small QFN packages.

  • Low 85 fs integrated jitter minimizes bit error rate and increases design margin 
  • When combined with a MEMS oscillator, quartz-related issues are eliminated including jitter degradation because of noise coupling onto a crystal interface, activity dips/frequency jumps and vibration sensitivity
