Abstract
An active routing circuit. In representative embodiments, the active routing circuit includes a channel switch which includes a transceiver and a switch. The transceiver has first data line, second data line, drive/receive control line, and receiver select control line. The switch has first contact connected to first data line, second contact connected to second data line, and switch control line. In a driver mode, the transceiver can receive data from first data line and output that data to second data line, and in receiver mode, can receive data from second data line and output that data to first data line. The transceiver can switch between driver mode and receiver mode in response to a signal. Data received from the second data line can be blocked in response to another signal. The switch can shift between connecting and disconnecting first contact to/from second contact in response to yet another signal.
