Micrel SM802108
The SM802108 is a member of the ClockWorks™ family of devices from Micrel and provides an extremely low-noise timing solution for GbE and 10GbE Ethernet 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 two LVPECL output clocks at 156.25MHz and another two at 125MHz.| Part No. | SM802108 |
