Hi All, I have a problem to solve,
I have a system which has a tuner chip and DSP chip, both are clocked by independent xtals. Tuner gives the baseband samples to DSP, and tuner is master and dsp is slave. Dsp does the demodulation of base band samples and does the audio decoding and generate audio, which is streamed out from DSP. Now if the tuner xtal is drifting then the dsp audio streaming needs to adjust to that drift, else buffer overflow or underrun happens as the sample rates doesn't match. How to design a control system such that a digital baseband frame of duration 'T' ms is mapped to audio and adjust the drift ? -ben
