Abstract:
Described is a chip comprising: a pull-up driver with a first impedance, the pull-up driver coupled to a node; a pull-down driver with a second impedance, the pull-down driver coupled to the node; and an equalizer coupled to the pull-up and pull-down drivers, wherein the equalizer is operable to be trained to deemphasize a signal driven on the node while maintaining the first and second impedances substantially constant.
