  • Patent number: 6831797
    Abstract: A programmable write equalization circuit includes a first digital clock that is used as a reference to indicate data rate, a second digital clock used to indicate write equalization quantization, a look-up table used to store waveforms used in equalizing the input from the first digital clock domain to the second digital clock domain, a counter used to indicate the number of bits within the look-up table that are to be used for each translation, a polarity detector used to detect the current state of the input data, a non-return-to-zero (NRZ) filter used to indicate the placement of data transitions and non-transitions, and a software interface including programmable registers to control each one of the parameters within the equalization circuit.
