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.
These devices are designed for compatibility with existing, as well as
evolving, telephone switching hardware and software architectures.
The UDLT chip–set consists of the MC145422 Master UDLT for use at the
telephone switch linecard and the MC145426 Slave UDLT for use at the remote
digital telset and/or data terminal.
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.
