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.

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 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

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).
