A method can include a digital oversampler oversampling an input data stream, a rate generator selecting a frequency that is not less than an expected frequency of the input data stream, a rate generator clock of the rate generator outputting a clock signal that has the selected frequency, determining whether a sample receiver has received at least one sample of the input data stream from the digital oversampler, and, responsive to a determination that the sample receiver has received at least one sample of the input data stream from the digital oversampler, incrementing a sample counter by each received sample. The method can also include a sample rate converter accumulating samples from the sample receiver at the rate of a “toothless” clock signal, determining whether an output of the sample counter is greater than zero, and, responsive to a determination that the output of the sample counter is greater than zero, an AND gate passing the “toothless” clock signal to the sample rate converter.
