The Cascade™ family of clock generators are engineered to deliver the highest level of clock tree integration, consolidating multiple clock ICs and oscillators into a single device. These MEMS clock generators integrate SiTime’s third-generation MEMS resonator and eliminate the crystal reference required by traditional clocks. By removing the dependency on quartz, all quartz related issues are eliminated. This integrated MEMS approach improves system robustness – no jitter degradation due to noise coupling with the crystal circuit, always-accurate frequency synthesis without crystal capacitive mismatching, 10 times more vibration resistant, and always-reliable startup in cold temperature and other harsh environmental conditions.
Cascade Platform™ MEMS-based clock generators feature 4 independent Frac-N PLLs, 4 inputs, up 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.
