Description
AI
The SY87701AL is a complete Clock Recovery and Data Retiming integrated circuit for data rates from 28Mbps up to 1.3Gbps NRZ. The device is ideally suited for SONET/SDH/ATM and Fibre Channel 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 SY87701AL also includes a link fault detection circuit.
