A method is provided. In this method, a clock signal and an input signal are received, where the input signal is a Manchester encoded signal. A unit interval (UI) number is incremented for each UI received upon receipt of a valid UI. The UI number is compared to a plurality of threshold values after the each increment of the UI number, where each threshold value is associated with at least one of a plurality of sum values. For each threshold value, once exceeded by the UI number, its sum value is incremented for each cycle of the clock signal, and a plurality of window lengths are calculated, where each window is calculated based at least in part on at least one of the sum values at predetermined values of the UI number.
