    62.5/125MHz Gigabit Ethernet, 4 Output,
    Ultra-Low Jitter Clock Synthesizer General Description Features The SM840004-11 clock synthesizer was designed for Generates 4 optimized LVCMOS clock outputs
    Gigabit Ethernet applications. The device design is RMS phase jitter @ 125MHz: ~55 fs (typ)
    optimized for 62.5MHz and 125MHz using a standard Integrated loop filter components
    25MHz fundamental parallel resonant crystal, with Operates with either a 3.3V or 2.5V supply
    unparalleled stability and accuracy over the full operating Power consumption 65mA (typ @ 2.5V)
    range, and provides an easy fit for Jitter and Phase Noise
    standards for these high performance interfaces. Selectable output frequency: 125MHz or 62.5MHz
    The SM840004-11 design includes a unique power Input frequency of 25MHz
    reduction methodology, along with a patented Fundamental parallel resonant crystal interface
    RotaryWaveв„ў architecture, that provides a stable clock Pin compatible with the ICS/IDT840004-11
    with very low noise for optimized performance. This yields Industrial temperature range: –40°C to +85°C
    an overall improved Bit Error Rate (BER) and improved
    waveform integrity. Green, RoHS-compliant and PFOS-compliant
