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 standalone 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.
