Abstract:
1. An electronic device comprising: a port coupled to a link partner, the port and the link partner to use closed-loop equalizer training to obtain receiver equalization coefficients for the receiver of the port and obtain transmitter equalization coefficients for the transmitter of the link partner; wherein during the closed-loop equalizer training, the link partner is to send a plurality of transmissions of a training set to the port, wherein each of the plurality of transmissions of the training set uses a different set of transmitter equalizer coefficients, and wherein the training set is used by the port to generate a set of receiver equalizer coefficients; and wherein the port determines which of the plurality of transmissions of the training set resulted in better signal quality, and the port informs the link partner to use the corresponding set of transmitter equalizer coefficients for transmitting packet data.
