SM840002 ClockWorks™ Dual 10-Gigabit/Gigabit Ethernet 62.5MHz, 125MHz, or 156.25MHz, Ultra-Low Jitter LVCMOS Clock Frequency Synthesizer General 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. Power supplies of either 2.5V or 3.3V are supported, with superior jitter and phase-noise performance. The device synthesizes a 62.5MHz, 125MHz, or 156.25MHz, lownoise LVCMOS output pair for Ethernet applications.
