3.3V 32-1250Mbps AnyRate

SY87701L

CLOCK AND DATA RECOVERY

Use lower-power SY87701AL for new designs

DESCRIPTION

The SY87701L 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 SY87701L also includes a link fault detection

circuit.

All support documentation can be found on Micrel’s web

site at www.micrel.com.
