Abstract:
1. A device, comprising: a node to couple to a wired link; a receiver having an input coupled to the node for receiving a baseband signal that includes data transmitted by another device having a transmitter, the transmitter having an output coupled to the node; and control logic to determine a performance metric, the performance metric comprising at least one of a timing margin corresponding to an error rate of the wired link and a voltage margin corresponding to the error rate of the wired link; wherein, during a calibration mode, an initial data rate of the wired link is increased from the initial data rate to an increased data rate that is a non-integer multiple of the initial data rate, and in response to the determination of the performance metric, a voltage swing of the transmitter output coupled to the node is adjusted.
