1. An integrated circuit (IC), comprising:
a transmitter to transmit a digital sequence via a set of drivers to a receiving device;
a transmit equalizer to equalize the digital sequence in association with multiple taps; and
a receiver to receive tap information from the receiving device, the tap information for setting at least one tap weight associated with at least one of the multiple taps of the transmit equalizer, each tap weight comprising a driver strength value for a given tap, the tap information configured to satisfy a predefined constraint.
