Single serdes transmitter driver design for both ethernet and peripheral component interconnect express applications

An apparatus for generating a serial output signal comprising:

• means for generating a plurality of digital filter control codes in response to a plurality of filter coefficients and a control signal, wherein said control signal selects between a plurality of communication specifications;
• means for generating a plurality of driver slice control codes in response to said plurality of digital filter control codes;
• and
• means for generating an output signal using a plurality of source series terminated driver slices according to a selected one of said plurality, of communication specifications in response to said plurality of driver slice control codes, a main cursor signal, a pre-cursor signal, and a post cursor signal.
