SM802108
Description
The SM802108 is a member of the Clock Works™ family of devices from Micrel and provides an extremely low-noise timing solution for Gb E and 10Gb E Ethernet clock signals. It is based upon a unique patented Rotary Wave® architecture that provides very low phase noise. The device operates from a 3.3V or 2.5V power supply and synthesizes two LVPECL output clocks at 156.25MHz and another two at 125MHz. The SM802108 accepts a 25 MHz crystal or LVCMOS reference clock. Data sheets and support documentation can be found on Micrel’s web site at: .micrel..
