    and Data Recovery General Description Features The SY69753AL is a complete Clock Recovery and
    Data Retiming integrated circuit for OC-3/STS-3
    applications at 155Mbps NRZ. The device is ideally
    suited for SONET/SDH/ATM applications and other
    high-speed data transmission systems.
    Clock recovery and data retiming is performed by
    synchronizing the on-chip VCO directly to the incoming
    data stream. The VCO center frequency is controlled by
    the reference clock frequency and the selected divide
    ratio. On-chip clock generation is performed through the
    use of a frequency multiplier PLL with a byte rate source
    as reference.
    The SY69753AL also includes a link fault detection
