LXT332

Dual T1/E1 Line Interface Unit with Crystal-less Jitter Attenuation

Datasheet

The LXT332 is a fully integrated Dual Line Interface Unit (DLIU) for both 1.544 Mbps (T1) and

2.048 Mbps (E1) applications. It features B8ZS/HDB3 encoders and decoders, and a constant

low output impedance transmitter for high return loss. Transmit pulse shape is selectable for

various line lengths and cable types.

The LXT332 incorporates an advanced crystal-less digital jitter attenuator, switchable to either

the transmit or receive side. This eliminates the need for an external quartz crystal. It offers

both a serial interface (SIO) for microprocessor control and a hardware control mode for stand-

alone operation.

The LXT332 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

■ PCM/Voice Channel Banks

■ Data Channel Bank/Concentrator

■ T1/E1 multiplexer

■ Computer to PBX interface (CPI & DMI)

■ SONET/SDH Multiplexers

■ Interfacing Customer Premises Equipment

to a CSU

■ Digital Access and Cross-connect Systems

(DACS)

■ Digital Loop Carrier (DLC) terminals

Product Features

■ Digital (crystal-less) jitter attenuation,

selectable for receive or transmit path, or

may be disabled

■ Complete line driver, data recovery and

clock recovery functions

■ Minimum receive signal of 500 mV, with

■ High transmit and receive return loss

selectable slicer levels to improve SNR

■ Constant low output impedance transmitter ■ Local, remote, and dual loopback functions

with programmable equalizer shapes pulses

■ Built-In Self Test with QRSS Pattern

to meet DSX-1 pulse template from 0 to

Generator

655 ft.

■ Transmit/Receive performance monitors

■ Meets or exceeds industry specifications

with Driver Fail Monitor (DFM) and Loss

including ITU G.703, ANSI T1.403, AT&T

of Signal (LOS) outputs

Pub 62411 and ITU-T G.742

■ Receiver jitter tolerance 0.4 UI from 40

■ Compatible with most industry standard

kHz to 100 kHz

framers

■ Available in 44-pin PLCC and 44-pin QFP
