Abstract: Techniques and mechanisms for providing signal communication with a configurable transceiver circuit. In an embodiment, an integrated circuit comprises transceiver circuitry including an output stage and current mirror circuitry. The output stage is coupled to receive a differential signal pair and to provide at least one output signal based on the differential signal pair. In another embodiment, configuration logic is operable to select between a first mode and a second mode of the transceiver circuit. The first mode includes the current mirror circuitry being disabled from providing a current signal to the output stage, and a first circuit path being closed to provide voltage to the output stage. The second mode includes the first circuit path being open and the current mirror circuitry being enabled to provide a current signal to the output stage.
