Abstract: A method relates generally to data reception for any of a plurality of data rates. In such a method, information and phases of a clock signal are obtained by a decision feedback equalizer. The information is equalized using the phases of the clock signal with the decision feedback equalizer to provide equalized sample streams. The equalized sample streams and the phases of the clock signal are provided to a selection circuit block. A first and a second phase of the phases are swapped, along with swapping a first and a second equalized sample stream corresponding to the first phase and the second phase, responsive to a data rate of the plurality of data rates.
