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.
Data sheets and support documentation can be found on
Micrelâs web site at www.micrel.com.
