CLOCK AND DATA RECOVERY

Micrel, Inc.

SY87701L

DESCRIPTION

FEATURES

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

■ 3.3V power supply

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.

■ Clock and data recovery from 32Mbps up to

1.25Gbps NRZ data stream, clock generation from

32Mbps to 1.25Gbps

■ Complies with Bellcore, ITU/CCITT and ANSI

specifications for applications such as OC-1, OC-3,

OC-12, ATM, FDDI, Fibre Channel and Gigabit

Ethernet as well as proprietary applications

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

another for clock recovery

The SY87701L also includes a link fault detection

circuit.

All support documentation can be found on Micrel’s web

site at www.micrel.com.

■ Selectable reference frequencies

■ Differential PECL high-speed serial I/O

■ Line receiver input: no external buffering needed

■ Link fault indication

■ 100k ECL compatible I/O

APPLICATIONS

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

packages (28-pin SOIC is available, but NOT

recommended for new designs.)

■ SONET/SDH/ATM OC-1, OC-3, OC-12, OC-24

■ Fibre Channel, Escon, SMPTE 259

■ Gigabit Ethernet/Fast Ethernet

■ Proprietary architecture up to 1.25Gbps
