Abstract:
1. A hard-end physical layer device (PHY) comprising: a hard-end transmitter configured to pre-equalize a forward channel and transmit first data over the forward channel to an easy-end receiver, wherein the hard-end transmitter is configured to pre-equalize the forward channel based on an estimate of characteristics of the forward channel determined without aid from a decision feedback equalizer at the easy-end receiver; a hard-end receiver configured to post-equalize a reverse channel and receive second data over the reverse channel from an easy-end transmitter; and a clock data recovery module configured to recover a clock from data received from a transmitter of an easy-end PHY, wherein the hard-end transmitter is configured to transmit the first data in accordance with the recovered clock, and wherein the hard-end receiver is configured to receive the second data in accordance with the recovered clock.
