AUDIO SAMPLE RATES
Figure 29 u-Law Companding
Figure 30 A-Law Companding
The WM8974 sample rates for the ADC and the DAC are set using the SR register bits. The cutoffs
for the digital filters and the ALC attack/decay times stated are determined using these values and
assume a 256fs master clock rate.
If a sample rate that is not explicitly supported by the SR register settings is required then the
closest SR value to that sample rate should be chosen, the filter characteristics and the ALC attack,
decay and hold times will scale appropriately.
