Abstract
In some embodiments, a chip includes first and second nodes, a variable voltage source, a transmitter, change detection circuitry, and control circuitry. The transmitter includes a driver coupled to the first and second nodes, and first and second resistive structures coupled between the first and second nodes, respectively, and the variable voltage source. The change detection circuitry detects changes in voltages of the first and second nodes following a change in voltage of the variable voltage source. The control circuitry determines whether the changes in voltages of the first and second nodes are consistent with the transmitter being coupled through interconnects to a remote receiver. Other embodiments are described and claimed.
