CLOCK AND DATA RECOVERY

Micrel, Inc.

SY87700V

FEATURES

■ 3.3V and 5V power supply options

■ SONET/SDH/ATM compatible

AnyRate

■ Clock and data recovery from 32Mbps up to

175Mbps NRZ data stream, clock generation from

32Mbps to 175Mbps

DESCRIPTION

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

The SY87700V 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.

another for clock recovery

■ 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

■ Complies with Bellcore, ITU/CCITT and ANSI

specifications such as OC-1, OC-3, FDDI, Fast

Ethernet, as well as proprietary applications

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

packages (28-pin SOIC is available, but not

recommended for new designs)

The SY87700V also includes a link fault detection

circuit.

APPLICATIONS

■ SONET/SDH/ATM OC-1/OC-3

■ Fast Ethernet

■ Proprietary architectures up to 175Mbps
