General Description

The SY87813L 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 SY87813L also includes a link fault detection circuit.
