摘要： 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.

摘要： Embodiments of the present disclosure are directed toward techniques and configurations for an optical apparatus to control optical power of the light source. In one embodiment, the apparatus may include a transmitter and receiver to transmit and receive optical signals over an optical communication channel, and a controller to cause the transmitter to transmit pulse signals at a first power level and detect a change in optical power in the channel, indicating a presence of a signal from another optical apparatus. The controller may confirm that the detected apparatus is capable of communications at a second power level (greater than the first level) and initiate data transmission at the second level. Upon detection of a failure in the channel, the controller may cause the transmitter to halt the data transmission and restart the pulse signals at the first power level. Other embodiments may be described and/or claimed.
