Abstract
Among other things, the present invention addresses timing issues related to a polarity control scheme in DFE implementation. Multiplexing that may be necessary for implementing a polarity control scheme is incorporated into multiplexing that may be required to convert half rate data into full rate data in a delay element of a DFE. Clocking signals are provided to a multiplexer that are encoded with polarity information. The various clock signals are generated using a clock generation circuit that incorporates polarity control.
