Overview
SM802110 ClockWorks™ CPRI 153.
6MHz Ultra-Low Jitter, LVPECL Frequency Synthesizer General Description The SM802110 is a member of the ClockWorks™ family of devices from Micrel and provides an extremely low-noise timing solution for CPRI clock signals.
It is based upon a unique patented RotaryWave® architecture that provides very low phase noise.
The device operates from a 3.
3V or 2.
5V power supply and synthesizes an LVPECL output clock at 153.
6MHz.
The SM802110 accepts a 30.
72MHz LVCMOS reference clock.
