SY87700/SY87701 CDR

EVALUATION KIT

SY87700/SY87701

EVALUATION BOARD

FEATURES

DESCRIPTION

■ 3.3V power supply:

The SY87700 and SY87701 Clock and Data Recovery

(CDR) chips are both high-performance ICs that are

designed to provide protocol-independent clock and data

recovery at any data rate between 32Mbps and 175Mbps

for the SY87700 and 32Mbps to 1.25Gbps for the SY87701.

Split V = +2V, GND = 0V

= –1.3V for 3.3V

= –3V for 5.0V

■ Simple switch configuration

■ PECL signal outputs

This document provides design and implementation

information, as well as a detailed description of the SY87700/

701 evaluation board.

■ Simple RDIN+, RDIN– PECL inputs

■ Simple REFCLK TTL input

The evaluation board is intended to provide a convenient

test and evaluation platform for the SY87700/701 CDR

device. This board can be used for many types of jitter

tests, including SONET compliance of the SY87700/701,

as well as PLL characterization.

■ SY87700: Clock and data recovery from 32Mbps up

to 175Mbps NRZ data stream, clock generation from

32Mbps to 175Mbps

■ SY87701: Clock and data recovery from 32Mbps up

to 1.25Gbps NRZ data stream, clock generation from

32Mbps to 1.25Gbps
