DS2149

5V T1/J1 Line Interface Unit

GENERAL DESCRIPTION

FEATURES

The DS2149 is a fully integrated LIU for long-

haul or short-haul T1 applications over twisted-

pair installations. It interfaces to two twisted-pair

lines—one pair for transmit and one pair for

receive through an appropriate network

interface. The device can be configured for

control through software or hardware mode.

Software control is accomplished over a serial

port, in hardware mode; individual pin settings

allow standalone operation. The device provides

a precise, crystal-less jitter attenuator that can be

placed in either the transmit or receive path.

CꢀFully Integrated Line Interface Unit (LIU)

CꢀPin Compatible with LevelOne LXT362

CꢀSupports Both Long Haul and Short Haul

CꢀCrystal-Less Jitter Attenuator
