Universal Digital Loop Transceivers (UDLT)
The MC145422 and MC145426 UDLTs are high–speed data transceivers that provide 80 kbps full–duplex data communication over 26 AWG and larger twisted–pair cable up to two kilometers in distance. Intended primarily for use in digital subscriber voice/data telephone systems, these devices can also be used in remote data acquisition and control systems. These devices utilize a 256 kilobaud modified differential phase shift keying burst modulation technique for transmission to minimize RFI/ EMI and crosstalk. Simultaneous power distribution and duplex data communication can be obtained using a single twisted–pair wire.
The devices employ CMOS technology in order to take advantage of their reliable low–power operation and proven capability for complex analog/digital LSI functions.
