T1/E1 Line Interface

&EATURES

'ENERAL $ESCRIPTION

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.

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.
