CS61577

T1/E1 Line Interface

Features

General Description

The CS61577 is a drop-in replacement for the

CS61574, and combines the complete analog transmit

and receive line interface for T1 or E1 applications in a

low power, 28-pin device operating from a +5V supply.

The CS61577 supports processor-based or stand-

alone operation and interfaces with industry standard

T1 and E1 framers.

Provides Analog Transmission Line

Interface for T1 and E1 Applications

•

Drop-in Replacement for CS61574 with

the Following Enhancements:

•

The receiver uses a digital Delay-Locked-Loop which is

continuously calibrated from a crystal reference to pro-

vide excellent stability and jitter tolerance. The receiver

includes a jitter attenuator optimized for minimum delay

in switching and transmission applications. The trans-

mitter provides internal pulse shaping to insure

compliance with T1 and E1 pulse template specifica-

tions.

- Lower Power Consumption

- Transmitter Short-Circuit

Current Limiting

- Greater Transmitter Immunity

to Line Reflections

Applications

- Software Selection Between 75Ω and

120Ω E1 Output Options

• Interfacing Network Equipment such as DACS and

Channel Banks to a DSX-1 Cross Connect

• Building Channel Service Units

ORDERING INFORMATION

- Internally Controlled E1 Pulse Width
