Abstract: A device receives a data signal and a reference timing signal provided from a first clock. The device includes a sample clock that operates independently from the first clock, wherein the sample clock outputs a sample clock signal that is asynchronous with the reference timing signal; a sampler for sampling a data signal in accordance with the sample clock signal and outputting a sampled data signal; and a resampler for resampling the sampled data signal according to a resampling ratio and outputting a resampled data signal such that a number of data samples in the resampled data signal within a synchronization time interval defined with respect to the reference timing signal equals a nominal number of data samples that would occur in the sampled data signal within the synchronization time interval when the sample clock signal was synchronized to the reference timing signal.
