MEMS Network Synchronizers

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. 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 due to noise coupling onto a crystal interface
• No activity dips/frequency jumps inherent to quartz
• 10x more resistant to vibration and board bending
