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.
