Abstract
A method is disclosed for tuning each channel of a high-speed SerDes cable link interface arranged in a configuration linking a local side physical layer to a remote side physical layer. The method includes initiating an operational state of high-speed SerDes cable link interface, identifying flow-control packet Op codes not cited for use by operational high-speed SerDes cable link interface, transmitting a flow control signal from the local side physical layer to the remote side physical layer to control the remote side physical layer to monitor the eye characteristics of the channels used by the local side physical layer to transfer data to the remote side physical layer, transferring eye characteristics acquired in the monitoring to the local side physical layer and processing the eye characteristics by the local side physical layer to generate equalization setting adjustments.
