3V, 622Mbps Clock and Data Recovery General Description The SY69754AL is a complete Clock Recovery and Data Retiming integrated circuit for OC-12/STS-12 applications at 622Mbps 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 SY69754AL also includes a link fault detection circuit.
