SM802120 ClockWorks™ Frequency Synthesizer

Micrel's SM802120 is a 125 MHz LVDS / 125 MHz HCSL ultra-low jitter frequency synthesizer

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 3.3 V or 2.5 V power supply and synthesizes eight differential 125 MHz output clocks, six LVDS, and two HCSL. The SM802120 accepts a 25 MHz crystal input.
