ClockWorks 10-Gigabit Ethernet, 312.5MHz, Ultra-Low Jitter LVPECL Clock Frequency Synthesizer
General Description
The SM843031-01 is a 10-Gigabit Ethernet, 312.5MHz LVPECL 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 312.5MHz, low-noise, LVPECL output for Ethernet applications. The crystal reference frequency used is 25MHz. The SM843031-01 is an excellent replacement for IDT FemtoClocks, with improved waveform integrity, and jitter. Data sheets and support documentation can be found on Micrel’s web site at: www.micrel.com.
