XRT73LC00A

E3/DS3/STS-1 LINE INTERFACE UNIT

MAY 2011

REV. 1.0.2

GENERAL DESCRIPTION

The XRT73LC00A DS3/E3/STS-1 Line Interface Unit

is a low power CMOS version of the XRT73L00A and

consists of a line transmitter and receiver integrated

on a single chip and is designed for DS3, E3 or

SONET STS-1 applications.

XRT73LC00A can be configured to support the E3

(34.368 Mbps), DS3 (44.736 Mbps) or the SONET

STS-1 (51.84 Mbps) rates.

In the transmit direction, the XRT73LC00A encodes

input data to either B3ZS (for DS3/STS-1

applications) or HDB3 (for E3 applications) format

and converts the data into the appropriate pulse

shapes for transmission over coaxial cable via a 1:1

transformer.

In the receive direction the XRT73LC00A performs

equalization on incoming signals, performs Clock

Recovery, decodes data from either B3ZS or HDB3

format, converts the receive data into TTL/CMOS

format, checks for LOS or LOL conditions and detects

and declares the occurrence of line code violations.

The XRT73LC00A also contains a 4-Wire

Microprocessor Serial Interface for accessing the on-

chip Command registers.
