SM802120 Datasheet, PDF (1/12 Pages) Micrel Semiconductor – ClockWorksTM 125MHz LVDS / 125 MHz HCSL Ultra-Low Jitter Frequency Synthesizer

SM802120
ClockWorks^TM 125MHz LVDS / 125 MHz
HCSL Ultra-Low Jitter
Frequency Synthesizer
General Description
The SM802120 is a member of the ClockWorks family of
devices from Micrel and provides an extremely low-noise
timing solution. 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 eight differential 125MHz output clocks,
six LVDS and two HCSL. The SM802120 accepts a 25
MHz crystal input.
Data sheets and support documentation can be found on
Micrel’s web site at: www.micrel.com.
