    10 Gigabit Ethernet and SONET, 6 output,
    Ultra-Low Jitter LVPECL Frequency
    Synthesizer General Description Features The SM843256 provides a low-noise timing solution for
    high speed, high accuracy synthesis of clock signals.
    Common applications include SONET, Gigabit Ethernet,
    10 Gigabit Ethernet, and similar networking standards. It
    includes a unique power reduction methodology, along
    with a patented RotaryWaveTM architecture that provides a
    very stable clock with very low noise.
    Power supplies of either 3.3V or 2.5V are supported, with
    superior jitter and phase noise performance. The device
    synthesizes different low noise LVPECL output
    frequencies such as 125MHz, 156.25MHz, 312.5MHz, and
    625MHz for Ethernet applications; 77.76MHz, 155.52MHz,
    311.04MHz, and 622.08MHz for SONET applications. The
    crystal reference frequencies used include 25MHz and
    19.44Mhz for Ethernet and SONET applications,
    respectively.
    The SM843256 is an excellent replacement for IDT Femtoclocks, with improved accuracy, power consumption,
    waveform integrity, and jitter.
