Abstract
A method for a mix mode driver to accommodate traces of different lengths includes storing in the mix mode driver a set of one or more control signals and coefficient signals for a trace length. The one or more control signals select a number of the stages to generate a variable amplitude data output signal. Each stage is operable to increase or decrease a data signal, and each of the coefficient signals determines the magnitude of increase or decrease of the data input signal by a stage. A method for operating the mix mode driver includes generating the variable amplitude data output signal with one or more of the stages, and providing the variable amplitude data output signal to a trace.
