Jitter Cleaners / Network Synchronizers

Cascade™ MEMS-based jitter cleaners feature 4 Frac-N PLLs with an integrated VCO and loop filter, flexible input-to-output frequency translation from 1 input to 10 outputs, wide frequency range from 8 kHz to 2.1 GHz, and a rich set of programmable features in a small 9 x 9 mm package. By integrating the MEMS resonator, these devices enable designers to create a clock-system-on-a-chip and eliminate all quality and reliability issues associated with traditional quartz-based clocks.

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

SiTime jitter cleaners feature up to 4 fractional PLLs, flexible input-to-output frequency translation with 4 inputs to 10 outputs, up to 12 outputs, wide frequency range, 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
   

Cascade™ MEMS-based network synchronizers features 4 independent time domains, 1 mHz to 4 kHz programmable loop bandwidth and DCO mode with 50-ppt resolution to frequency, and phase recovery from syncE and IEEE 1588. These devices also come with 4 Frac-N PLLs with an integrated VCO and loop filter, flexible input to output frequency translation, wide frequency range, and a rich set of programmable features in a small 9 x 9 mm package.
