摘要： A method of performing sample rate conversion in a data converter operating from an oversampling clock corresponding to a native sample rate and a native oversampling factor. A virtual sample rate and a virtual oversampling factor are selected proportional to the native sample rate and the native oversampling factor. A data stream having a data sample rate is sampled by the virtual oversampling factor. The data stream is also resampled with a resampling ratio approximating a ratio of the data sample rate to the virtual sample rate.
