DIGITAL DIFFERENTIAL SIGNAL SWITCHING UNIT Russian patent published in 2005 - IPC

FIELD: computer engineering; construction of multichannel devices for information input in digital wire communication systems.

SUBSTANCE: proposed switching unit designed for executing function of address switching of plurality of digital differential input signals of any bipolar and two- or three-level self-synchronizing serial code to two TTL digital information outputs has first and second attenuators, two-port multiplexer-demultiplexer, inputs of first and second components of digital differential signals, two comparators, and two digital information outputs, as well as ten resistors; ratings of first through fourth resistors are equal; ratings of fifth, seventh, and ninth resistors are equal to those of sixth, eighth, and tenth resistors, respectively; ratings of fifth and sixth resistors are equal to those of parallel-connected seventh and tenth or eighths and tenth resistors, respectively.

EFFECT: enhanced speed and simplified design of switching unit.
