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.
