SiT95145 Cascade ClkSoC™ High-Performance 10-output MEMS Jitter Cleaner Description The Cascade ClkSoC™ SiT95145 is a single-chip MEMS clock jitter cleaner optimized for the highest level of clock tree integration, consolidating multiple clock ICs and oscillators into a single device. Its low noise quad-PLL architecture and programmable output drivers can deliver up to 10 differential or 20 LVCMOS low jitter clock outputs. This ClkSoC™ supports 4 additional clock inputs with fracN dividers, enabling virtually any input to output frequency translation configurations from 8 kHz to 2.1 GHz. The SiT95145 integrates a SiTime third-generation ApexMEMS resonator to completely eliminate the need for external discrete crystal references required by traditional clock generators.
