Abstract
This disclosure describes techniques for extending a range of bidirectional bus communications through the use of a differential signal path. The disclosed techniques include first separating the bidirectional bus into first and second unidirectional buses that transmit and receive signals, respectively, and then communicating the signals from the first and second unidirectional buses over a differential signal path. The separation of the bidirectional bus into the first and second unidirectional buses is performed using logic circuitry that blocks or permits communication between a given one of the first and second buses and the bidirectional bus based on whichever one of the first and second buses becomes dominant first. If the logic circuitry determines that the first bus becomes dominant before the second bus, the logic circuitry permits communications between the first bus and the bidirectional bus and blocks communications between the second bus and the bidirectional bus.
