Abstract
Aspects of the disclosure relate to asynchronous sampling rate conversion of digital data. A sampling rate conversion module may use, for sampling rate conversion, a bank of subfilters corresponding to a polyphase interpolator. The specific subfilters and/or filter coefficients to be used for generation of output samples may be based on a rate control value. The rate control value may be determined based on a sampling rate used for input samples of the sampling rate converter and a read-out rate associated with samples, generated by the sampling rate converter, stored in an output buffer. A phase-locked loop (PLL) or other control loop may be used to maintain the rate control value at an appropriate level to negate the effects of temperature variations, noise, or any other system variations on the sampling rates.
