Product Summary

The LXT317PE is a fully integrated, long-haul transceiver for Digital European Cordless Telephone (DECT) base station interface applications at 1.152 Mbps. The LXT317PE operates over twisted-pair cable to a maximum of 43 dB (3.5 km at 0.6 mm, 40 nF/km cable) with no external components. The LXT317PE offers selectable HDB3 encoding/decoding, and unipolar or bipolar data I/O. The device also offers a variety of diagnostic features including loopbacks and Loss of Signal monitoring. Its advanced double-poly, double-metal CMOS process requires only a single 5-volt power supply. The applications of the LXT317PE include DECT base stations to switch/ PBX interface, NTU (interface to E1 Service), LAN bridge and Private network data pump.
