Abstract
A method and apparatus for duty cycle distortion compensation is disclosed. In one embodiment, an integrated circuit includes a differential signal transmitter having a main data path and a compensation data path. The main data path includes a first and second differential driver circuits each having output terminals coupled to a differential output. A transmission controller is configured to transmit data into the main and compensation data paths, the data corresponding to pairs of sequentially transmitted bits including an odd data bit followed by an even data bit, and further configured to determine respective duty cycle widths for each of the odd and even data bits as received by the transmission controller. The transmission controller is configured to cause the first and second driver circuits to equalize the respective duty cycle widths of the odd and even data bits, as transmitted, based their respective duty cycle widths as received.
