XRT73L02
2 CHANNEL E3/DS3/STS-1 LINE INTERFACE UNIT
JANUARY 2001
REV. P1.1.0
GENERAL DESCRIPTION
The XRT73L02 Dual Channel E3/DS3/STS-1 Trans-
ceiver IC consists of two fully integrated transmitter
and receiver line transceivers designed for E3, DS3
or SONET STS-1 applications.
Each channel can be configured to support the E3
(34.368 Mbps), DS3 (44.736 Mbps) or the SONET
STS-1 (51.84 Mbps) rates. Each channel can be con-
figured to operate in a mode/data rate that is indepen-
dent of the other channel.
In the transmit direction, each channel in the
XRT73L02 encodes input data to either B3ZS or
HDB3 format and converts the data into the appropri-
ate pulse shapes for transmission over coaxial cable
via a 1:1 transformer.
In the receive direction, the XRT73L02 can perform
Equalization on incoming signals, perform Clock Re-
covery, decode data from either B3ZS or HDB3 for-
mat, convert the receive data into TTL/CMOS format,
check for LOS or LOL conditions and detect and de-
clare the occurrence of Line Code Violations.
