Abstract
A signaling system having an equalizing transmitter and equalizing receiver. The equalizing transmitter transmits a signal to a receive circuit. A first sampling circuit within the equalizing receiver samples the signal to determine whether the signal exceeds a first threshold, and a second sampling circuit within the equalizing receiver samples the signal to determine whether the signal exceeds a second threshold. A drive strength of the equalizing transmitter and a drive strength of an equalizing signal driver within the equalizer are adjusted based, at least in part, on whether the first signal exceeds the first and second thresholds.
