CDB61577 T1/E1 LINE INTERFACE Datasheet

Features: www.DataSheet4U.com CS61577 T1/E1 Line Interface Features General Description The CS61577 is a drop-in replacement f or the CS61574, and combines the comple te analog transmit and receive line int erface for T1 or E1 applications in a l ow power, 28-pin device operating from a +5V supply. The CS61577 supports proc essor-based or standalone operation and interfaces with industry standard T1 a nd E1 framers. The receiver uses a digi tal Delay-Locked-Loop which is continuo usly calibrated from a crystal referenc e to provide excellent stability and ji tter tolerance. The receiver includes a jitter attenuator optimized for minimu m delay in switching and transmission a pplications. The transmitter provides i nternal pulse shaping to insure complia nce with T1 and E1 pulse template speci fications. • Provides Analog Transm ission Line Interface for T1 and E1 App lications • Drop-in Replacement for CS61574 with the Following Enhancements : - Lower Power Consumption - Transmitter Short-Circuit Current Li.
