LXT331

Dual T1/E1 Line Interface Unit

Datasheet

The LXT331 is a Dual Line Interface Unit (DLIU) optimized for North America 1.544 Mbps

(T1) and international 2.048 Mbps (E1/CEPT) applications. It features a constant low output

impedance transmitter for high return loss. Transmit pulse shape is selectable for various line

lengths and cable types. The data recovery circuit also offers selectable slicer ratios for T1 or E1

applications.

The LXT331 offers both a serial interface (SIO) for microprocessor control and a hardware

control mode for stand-alone operation.

The LXT331 offers a variety of advanced diagnostic and performance monitoring features. It

uses an advanced double-poly, double-metal CMOS process and requires only a single 5-volt

power supply.

Applications

■ Digital Access and Cross-connect Systems ■ Digital Loop Carrier (DLC) terminals

(DACS)

■ T1/E1 Multiplexer

■ Cost efficient AFE for Digital Backend

ASICS

■ SONET/SDH Multiplexers

■ Analog LOS using PMRK/NMRK

Product Features

■ Complete line driver and data recovery

■ Minimum receive signal of 500 mV, with

selectable slicer levels (E1/DSX-1) to

improve SNR

functions

■ Constant low output impedance transmitter

with a programmable equalizer that shapes ■ Analog loopback function

pulses to meet the DSX-1 pulse template

■ Transmit performance monitors with

from 0 to 655 ft.

Driver Fail Monitor (DFM) output for

transmit driver short circuit detection

■ High transmit and receive return loss

■ Meets or exceeds industry specifications

including ITU G.703 and ANSI T1. 102-

1993

■ Transmit Driver Performance Monitor

(DPM) output on external pins MTIP and

MRING

■ Compatible with industry standard framers ■ Available in 44-pin PLCC and 44-pin QFP
