ABSTRACT:
A method for decoding a Manchester-II encoded DISPLAYPORT compatible signal is provided. In this method, several counters are reset. A unit interval (UI) counter is incremented for each UI received upon receipt of a valid UI, and the value of the UI counter is compared to a plurality of threshold values after the UI counter is incremented. When the value of the UI counter exceeds each of the threshold values, for each clock cycle, a sum counter is incremented corresponding to the exceeded threshold value, and a plurality of window lengths are calculated, where each window is calculated based at least in part on the value of one of the sum counters at predetermined values of the UI counter.
