LXT361 - E1/T1 LH/SH Transceiver Note - Not recommended for new designs; End-of-Life in process-see PCN

The LXT361 is a fully integrated, combination transceiver for T1/E1 ISDN Primary Rate Interface (ISDN PRI) and general T1/E1 Long and Short Hual applications. The device operates over 0.63 mm (22 AWG) twisted-pair cables for 0 to 2 km (6 kft) and offers Line Build Outs (LBO) and pulse equalization settings for all T1 and E1 Line Interface Unit (LIU) applications. The LXT361 features an Intel or Motorola compatible parallel port for microprocessor control. The LXT361 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 available. The LIU provides loss of signal monitoring and a variety of diagnostic loopback modes.
