CLOCK AND DATA RECOVERY

SY87700L

FEATURES

DESCRIPTION

■ Industrial temperature range (–40°C to +85°C)

■ 3.3V power supply

The SY87700L is a complete Clock Recovery and Data

Retiming integrated circuit for data rates from 32Mbps

up to 175Mbps NRZ. The device is ideally suited for

SONET/SDH/ATM 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.

■ SONET/SDH/ATM compatible

■ Clock and data recovery from 32Mbps up to

175Mbps NRZ data stream

■ Two on-chip PLLs: one for clock generation and

another for clock recovery

■ Selectable reference frequencies

■ Differential PECL high-speed serial I/O

■ Line receiver input: no external buffering needed

■ Link Fault indication

The SY87700L also includes a link fault detection

circuit.

■ 100K ECL compatible I/O

■ Complies with Bellcore, ITU/CCITT and ANSI

specifications for applications such as OC-1 and

OC-3

APPLICATIONS

■ SONET/SDH/ATM OC-1 and OC-3

■ Fast Ethernet

■ Available in 28-pin SOIC and 32-pin EP-TQFP

packages

■ Proprietary architecture up to 175Mbps
