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.
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.
Applications
Interfacing Network Equipment such as DACS and
Channel Banks to a DSX-1 Cross Connect
Building Channel Service Units
