The Si5374 precision clock accepts dual clock inputs ranging from 2 kHz to 710 MHz and generates dual clock outputs ranging from 2 kHz to 945 MHz and select frequencies to 1.4 GHz. The Si5374 precision clock is based on Silicon Labs' 3rd-generation DSPLL® technology which provides any-rate frequency synthesis in a highly integrated PLL solution that eliminates the need for external VCXO and loop filter components. The Si5374 supports loop BW values below 5 Hz.
