GENERAL DESCRIPTION

FEATURES

The DS21349 is a fully integrated LIU for long- ꢀ Fully Integrated Line Interface Unit (LIU)

haul or short-haul T1 applications over twisted- ꢀ Pin Compatible with LevelOne LXT362

pair installations. It interfaces to two twisted-pair ꢀ Supports Both Long Haul and Short Haul

lines—one pair for transmit and one pair for ꢀ Crystal-Less Jitter Attenuator

receive through an appropriate network ꢀ Jitter Attenuator Programmable for Transmit

interface. The device can be configured for

or Receive Path

control through software or hardware mode. ꢀ Meets ANSI T1.102, T1.403, T1.408, and

Software control is accomplished over a serial AT&T 62411

port in hardware mode; individual pin settings ꢀ Usable Receive Sensitivity of 0dB to -36dB

allow stand-alone operation. The device provides

a precise, crystal-less jitter attenuator that can be

placed in either the transmit or receive path.

That Allows the Device to Operate on

0.63mm (22AWG) Cables Up to 6k Feet in

Length

ꢀ Five Line Build-Out Settings for Short-Haul
