LXT362

Integrated T1 LH/SH Transceiver for DS1/DSX-1 or PRI Applications

Datasheet

The LXT362 is a fully integrated, combination transceiver for T1 ISDN Primary Rate Interface

and general T1 long and short haul applications. It operates over 22 AWG twisted-pair cables

from 0 to 6 kft and offers Line Build Outs and pulse equalization settings for all T1 Line

Interface Unit (LIU) applications.

LXT362 provides both a serial port for microprocessor control (Host mode) as well as stand-

alone operation (Hardware mode). The device incorporates advanced crystal-less digital jitter

attenuation in either the transmit or receive data path starting at 3 Hz. B8ZS encoding/decoding

and unipolar or bipolar data I/O are selectable. Loss of signal monitoring and a variety of

diagnostic loopback modes can also be selected.

Applications

■ ISDN Primary Rate Interface (ISDN PRI)

■ CSU/NTU interface to T1 Service

■ Wireless Base Station interface

■ T1 LAN/WAN bridge/routers

■ T1 Mux; Channel Banks

■ Digital Loop Carrier - Subscriber Carrier

Systems
