ABSTRACT:
A method and system for is disclosed for reducing intersymbol interference in a stream of data bits to be transmitted over a transmission medium. Aspects of the present invention include a phase delayed clock generated from a reference clock that produces an edge on sub-bit boundaries; and a digital filter coupled to the phase delayed clock for performing equalization on the data bits, wherein the phase delayed clock causes the digital filter to perform partial clock switching, such that equalization is performed on the data bits on-sub-bit boundaries.
