SM840002 Description
The SM840002 is a dual 10-Gigabit Ethernet and Gigabit Ethernet, 62.5MHz, 125MHz, or 156.25MHz LVCMOS clock frequency synthesizer and a member of the ClockWorks™ family of devices from Micrel. It provides a low-noise timing solution for high-speed, high-accuracy synthesis of clock signals. It includes a patented RotaryWave® architecture that provides a very stable clock with very-low noise.
