A sample rate converter for converting a data stream having a first base sampling frequency to a data stream having a second base sampling frequency. Up-sampling circuitry receives first oversampled data having a first oversampling ratio with respects to the first base frequency and outputs second oversampled data having a second oversampling ratio with respects to the first base sampling frequency. Resampling circuitry resamples the second oversampled data by a resampling frequency ratio of integers representing a ratio of the first and second base frequencies and generates third oversampled data having the second oversampling ratio with respects to the second base frequency. Down-sampling circuitry then down-samples the third oversampled data and generates fourth oversampled data having the first oversampling ratio with respects to the second base frequency.
