ABSTRACT:
A system for providing multiple communication channels over a single voltage isolation link includes first circuitry for multiplexing a plurality of digital data inputs from a plurality of communication channels onto the single voltage isolation link. Second circuitry de-multiplexes the plurality of digital data inputs from the single voltage isolation link to the plurality of communication channels. An RF isolator is used for providing the single voltage isolation link.
