Abstract
Equalization circuitry for receiving a digital data signal includes both feed-forward equalizer ('FFE') circuitry and decision-feedback equalizer ('DFE') circuitry. The FFE circuitry may be used to give the DFE circuitry a signal that is at least minimally adequate for proper start-up of the DFE circuitry. Thereafter, more of the burden of the equalization task may be shifted from the FFE circuitry to the DFE circuitry.
