Classification: CPC G  H  Y | IPC G  H

Claim 10:
11. A method of operating a device configured to be coupled to and transmit and receive data via a wired link, wherein the device includes:
a transmit circuit to couple with the wired link and to transmit data from the device to a second device, and
a receive circuit to couple to the wired link and to receive data transmitted by the second device,
wherein the transmit circuit and receive circuit of the device are configurable for bi-directional communication of information over the wired link with the second device at various data rates, where a maximum data rate of the various data rates is a non-integer multiple of an initial data rate of the various data rates;
the method comprising:
enabling the transmit circuit to communicate information over the wired link to the second device at the various data rates, including the initial data rate of the various data rates;
determining a metric for communication of information over the wired link determined for each of two or more of the various data rates;
determining a maximum data rate of the various data rates, wherein the maximum data rate is a non-integer multiple of the initial data rate of the various data rates and is determined based on the metric for communication of information over the wired link with the second device for each of two or more of the various data rates;
increasing a voltage swing of the transmit circuit if the maximum data rate is less than a target data rate;
decreasing a supply voltage of the transmit circuit if the maximum data rate is greater than the target data rate; and
decreasing the voltage swing of the transmit circuit if the maximum data rate is greater than the target data rate.
