Abstract
A method and corresponding apparatus for aligning a data signal with a corresponding clock signal include oversampling the data signal based on the corresponding clock signal and generating corresponding data samples. An indication of skew between the data signal and the corresponding clock signal is detected based on data samples. A variable delay line coupled to the data signal is then adjusted based on the indication of skew detected. According to at least one example implementation, the data signal is oversampled based on the corresponding clock signal and multiple time-shifted versions of the corresponding clock signal. At least one signal of the corresponding clock signal and the multiple time-shifted versions of the corresponding clock signal is employed in sampling the data signal at a potential transition edge of the data signal.
