Si5022/Si5023

MULTI-RATE SONET/SDH CDR IC WITH LIMITING AMP

Features

High Speed Clock and Data Recovery device with Integrated Limiting Amp:

Applications

Description

The Si5022/23 is a fully integrated, high performance limiting amp and clock and

data recovery (CDR) IC for high-speed serial communication systems. It extracts

timing information and data from a serial input at OC-48/12/3, STM-16/4/1, or

Gigabit Ethernet (GbE) rates. Support for 2.7 Gbps data streams is also provided

for OC-48/STM-16 applications that employ forward error correction (FEC). An

external reference clock is not required; applications with or without an external

reference clock are supported. Silicon Laboratories’ DSPLL™ technology

eliminates sensitive noise entry points thus making the PLL less susceptible to

board-level interaction and helping to ensure optimal jitter performance.

The Si5022/23 represents a new standard in low jitter, low power, small size, and

integration for high speed LA/CDRs. It operates from either a 3.3 V (Si5023) or

2.5 V (Si5022) supply over the industrial temperature range (–40°C to 85°C).
