LXT360
Integrated T1/E1 LH/SH Transceiver for DS1/DSX-1 or PRI Applica-
tions
Datasheet
The LXT360 is a fully integrated, combination transceiver for T1/E1 ISDN Primary Rate
Interface (ISDN PRI) and general T1/E1 long and short haul applications. It operates over 0.63
mm (22 AWG) twisted-pair cables for 0 to 2 km (6 kft) and offer Line Build Out (LBO) and
pulse equalization settings for all T1 and E1 Line Interface Unit (LIU) applications.
LXT360 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/HDB3 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 selected2.
