Original Abstract Submitted

aspects relate to techniques for controlling signal voltage levels across a wired data link for data communication between apparatuses. a first device can advertise multiple supported signal voltage levels to a peer device connected by the wired data link. the devices can implement the same signal voltage level(s) or different signal voltage levels. the peer devices can compare and select a compatible signal voltage level for data communication. the first device can provide a signal voltage indication signal that is configurable to a plurality of voltage levels corresponding to a plurality of signal voltages. at least one of the plurality of voltage levels can indicate that the first device can operate the data link at a plurality of signal voltages. in some examples, the wired data link can be a peripheral component interconnect express (pcie) link.
