描述 Description

Use lower-power SY87701AL for 3.3V systemsThe SY87701V is a complete Clock Recovery and Data Retiming integrated circuit for data rates from 32Mbps up to 1.25Gbps 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 SY87701V also includes a link fault detection circuit.
