DESCRIPTION
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.
This document provides design and implementation
information, as well as a detailed description of the SY87700/
701 evaluation board.
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.
