Hello,
How long does it take for Codec Data In to make its way to the DAC output? and ADC input to make it to the Codec Data Out?
Say the I2S bus holds data in Sample Frame 0. That data is shifted into the Codec during Frame 0. Does the 21/fs interpolation time start at the WCLK pulse of Frame 1? Finishes in frame21? DAC output gets updated at WCLK pulse of Frame 22?
Similarly, if there is an analog voltage present and stable at the ADC inputs at the time of the WCLK pulse in frame 0. 17/fs starts in Frame 0, decimation is finished in Frame 16. Does the ADC result get shifted onto the I2S bus in Frame 17?
Digital word in (Frame 0) --> DAC output --> ADC input --> Digital word out (Frame 41)? 18 + 23?
Thanks for your help,
Curt
