Abstract

A method of operating an Ethernet transceiver includes initializing the Ethernet transceiver during a training mode of operation by monitoring background link operating characteristics with on-chip circuitry during a non-data-transfer interval to establish a baseline alien crosstalk value. Training data is then transmitted at a first transmit power level and first data rate to a link partner during a data transfer interval. The link is monitored with the on-chip circuitry during the data transfer interval to detect feedback indicating alien crosstalk effects to neighboring Ethernet links due to the transmitting. The first data rate and/or first transmit power level is then adjusted to an adjusted second data rate and/or second transmit power level based on the feedback. The Ethernet transceiver is then operated in a normal data transfer mode utilizing the adjusted second data rate and/or transmit power level.
