GENERAL DESCRIPTION
The XR-T7296 is a fully integrated PCM Line Driver IC
intended for DS3 (44.736Mbps) or E3 (34.368Mbps)
applications. It can also be used for transmitting SONET
STS-1 (51.84Mbps) signals over coaxial cable. The IC is
designed to complement either XR-T7295 DS3/SONET
STS-1 or XR-T7295E E3 Integrated Line Receivers. The
XR-T7296 converts input clock and dual-rail unipolar data
into AMI pulses according to AT&T Technical Advisory
No. 34 or CCITT G.703 recommendations.
The device provides B3ZS (DS3) or HDB3 (E3) encoding
functions for data to be transmitted to the line. A
complimentary decoder circuit is also included in the chip
for decoding received signals from an external line
receiver. Both encoder and decoder functions can be
disabled independently through external control pins. In
the receive direction, coding errors and bipolar violations
are detected and flagged at an output pin.
On-chip pulse shaper circuitry eliminates normally
required external components for line equalization to
meet the cross-connect template. For system level
trouble-shooting and testing, both local and remote
loop-backs are possible with the built-in loop-back circuit.
The XR-T7296 is manufactured using BiCMOS
technology and is packaged in a 28-pin PDIP or SOJ
packages. The device requires a single 5V power supply
and consumes a maximum power of 700mW. (Line
current feed + device dissipation).
