Abstract: A redriver includes a plurality of channels coupled to an interface, a number of detectors coupled to the plurality of channels, and a controller that determines an orientation of the interface based on states detected by the number of detectors. The controller determines that the interface is in a first orientation when a first combination of states is detected for the plurality of channels, and determines that the interface is in a second orientation when a second combination of states is detected for the plurality of channels.

Abstract: A protocol can specifie a power-sourcing voltage range that indicates power sourcing capabilities. Additional power sourcing capabilities can be communicated using voltage variations within the power-sourcing voltage range. A power-sourcing device can provide power to an external power-sinking device over a wired connection containing a plurality of wires. A voltage control circuit can be configured to drive a voltage over a wire of the plurality of wires. Processing circuitry can communicate, using the voltage control circuit, first power-sourcing capabilities to the external power-sinking device by setting the voltage over the wire to a value within the power-sourcing voltage range. The processing circuitry can also communicate, using the voltage control circuit, the additional power sourcing capabilities of the power-sourcing device using voltage variations on the wire, the voltage variations maintaining voltage on the wire within the power-sourcing voltage range.
