描述 Description

DESCRIPTION
The SY87700L 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.FEATURES
■Industrial temperature range (–40°C to +85°C)
■3.3V power supply
■SONET/SDH/ATM compatible
■Clock and data recovery from 32Mbps up to
?? 175Mbps NRZ data stream, clock generation from 32Mbps to 175Mbps
■Two on-chip PLLs: one for clock generation and 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 for applications such as OC-1 and OC-3 as well as proprietary applications
■Available in 32-pin EPAD-TQFP and 28-pin SOIC packages (28-pin SOIC is available, but is not recommended for new designs.)
