CLOCK AND DATA RECOVERY

Micrel, Inc.

SY87702L

FEATURES

DESCRIPTION

■ 3.3V power supply

The SY87702L is a complete Clock Recovery and Data

retiming integrated circuit for data rates from 28Mbps up to

2.5Gbps NRZ. The device is ideally suited for SONET/SDH/

ATM, Fibre Channel, and Gigabit Ethernet applications, as

well as other high-speed data transmission applications.

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-

■ Complies with Bellcore, ITU/CCITT and ANSI

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

OC-12, OC-48*, and ATM

■ Compatible with FDDI, Gigabit Ethernet, Fibre

Channel, 2X Fibre Channel, SMPTE 259 and 292, and

proprietary applications

■ Low power

■ Clock and data recovery from 28Mbps up to 2.5Gbps chip clock generation is performed through the use of a

NRZ data stream

frequency multiplier PLL and can be used as a Clock

Multiplier Unit (CMU). The integrated CMU can provide this

clock signal at the TCLK outputs. Additionally, the TCLK

output can be selected to provide a copy of the RCLK

frequency.

For SONET/SDH applications, the SY87702L includes a

Link Fault Detection circuit. This circuit, enabled by the output

of an optical module driving the CD input low, causes the

recovery PLL of the SY87702L to lock to the reference

clock's multiplied frequency under Loss-of-Signal conditions.

This low jitter clock is provided at the RCLK outputs and is

at the same frequency as that provided at the TCLK output.

■ Selectable reference frequencies via programmable

multiplier

■ Differential PECL and CML high-speed serial outputs

■ Line receiver input: no external buffering needed

■ Link fault indication

■ 100K ECL compatible I/O

■ Available in 64-Pin EP-TQFP package

*Meets OC-48 Jitter Tolerance and Transfer

APPLICATIONS

■ Transponders and section repeaters

■ Multiplexer's: access, add drop (ADM), and terminal

(TM)

■ SONET/SDH/ATM: -based transmission systems,

modules, and test equipment

■ Terabit routers and broadband cross-connects

■ Fibre optic test equipment

■ HDTV switching and transmission
