ABSTRACT:
There is disclosed, an active termination circuit includes a transmitter adapted to be coupled to a bidirectional conductor, a receiver also adapted to be coupled to the bidirectional conductor, a first impedance adapted to be switched to couple to the bidirectional conductor to match the input impedance of the receiver to a characteristic impedance of the bidirectional conductor to which it is adapted to be coupled when the receiver is in the receive mode, and a second impedance adapted to be switched to couple the bidirectional conductor to match the output impedance of the transmitter to the characteristic impedance of the bidirectional conductor to which it is adapted to be coupled when the transmitter is in the transmit mode.
