    • In some embodiments, a chip includes transmitters to transmit differential signals on conductors; and current mode circuitry selectively to modulate a common mode voltage of the differential signals, so as to communicate data. In other embodiments, a system includes a first chip to transmit first and second differential signals on conductors, and a second chip. The second chip includes receivers to receive the first and second differential signals from the conductors and provide received signals representative thereof, and current mode circuitry selectively to modulate a common mode voltage of either the first or second differential signals to communicate data and wherein the first chip includes common mode detection circuitry to detect changes in the common mode voltage. Other embodiments are also described and claimed.
