XRT73L04B
4 CHANNEL DS3/E3/STS-1 LINE INTERFACE UNIT
OCTOBER 2003
REV. 1.0.1
GENERAL DESCRIPTION
The XRT73L04B, 4-Channel, DS3/E3/STS-1 Line In-
terface Unit is a low power CMOS version of the
XRT73L04A and consists of four independent line
transmitters and receivers integrated on a single chip
designed for DS3, E3 or SONET STS-1 applications.
Each channel of the XRT73L04B 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 configured to operate in a mode/data
rate that is independent of the other channels.
In the transmit direction, each channel encodes input
data to either B3ZS (DS3/STS-1) or HDB3 (E3) for-
mat and converts the data into the appropriate pulse
shapes for transmission over coaxial cable via a 1:1
transformer.
In the receive direction, the XRT73L04B performs
equalization on incoming signals, performs Clock Re-
covery, decodes data from either B3ZS or HDB3 for-
mat, converts the receive data into TTL/CMOS for-
mat, checks for LOS or LOL conditions and detects
and declares the occurrence of Line Code Violations.
