Abstract
A transceiver includes a first receiver having an input connected to a first I/O port of the transceiver and an output connected to an output port of the transceiver and a second receiver having an input connected to a second I/O port of the transceiver and an output connected to the output port of the transceiver. A first driver has an input connected to an input port of the transceiver and an output connected to the first I/O port, and a second driver has an input connected to the input port of the transceiver and an output connected to the second I/O port. The transceiver has a first state in which the first receiver and second driver are enabled and propagate signals from the first I/O port to the output port and from the input port to the second I/O port and the second receiver is disabled and presents a high impedance to the output port, and a second state in which the second receiver and first driver are enabled and propagate signals from the second I/O port to the output port and from the input port to the first I/O port and the first receiver is disabled and presents a high impedance to the output port.
