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.

Data sheets and support documentation can be found on

Micrel’s web site at www.micrel.com.
