SY69753L Datasheet | Micrel Semiconductor

3.3V, 125Mbps, 155Mbps Clock and Data Recovery Use lower-power SY69753AL for new designs General Description The SY69753L is a plete 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 ining 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...
