SM802109 Synthesizer


The SM802109 is a ClockWorks™ PCI-3 Quad 100 MHz ultra-low jitter, HCSL frequency synthesizer


The SM802109 is a member of the ClockWorks™ family of devices from Micrel and provides an extremely low-noise timing solution for PCI-Express clock signals. It is based on 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 four HCSL output clocks at 100 MHz. The SM802109 accepts a 25 MHz crystal or LVCMOS reference clock. Datasheet
