SY87721L数据手册集成电路（IC）的应用特定时钟/定时规格书PDF

描述 Description

The SY87721L is a complete Clock Recovery and Data retiming integrated circuit for data rates from 28Mbps up to 2.7Gbps NRZ including SONET FEC data rates. Included in the device, is a fully integrated Clock Multiplier Unit (CMU) that is capable of generating frequencies that cover the same data rate range as the CDR. The device is ideally suited for SONET/SDH/ATM, Fibre Channel, and Gigabit Ethernet applications, as well as other high-speed data transmission applications.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 or code group rate source as reference.
