    Abstract: A re-driver circuit includes a first channel comprising a receiver to receive an input signal from a first port to the re-driver circuit and a driver to receive a signal from the receiver and drive an output signal of the re-driver circuit through a second port. A second channel is also provided and is in parallel with the first channel and includes a bidirectional path switch. A channel control unit determines whether the input signal is indicative of a higher speed mode or of a lower speed mode and enables one of the first and second channels while disabling the other of the channels based on the determined mode. The first and second channels share the first and second ports.
