Audio clock generation in 3104 : parameter (P,K,R,J...) choice

Hi everyone,

We need to program the AIC3104 for a sampling rate of 8kHz.

We use a BCLK of 256khz. As we learned on this forum, we have to calculate our parameter with fs(ref) of 48khz and then divide it by 6 to get our sampling rate of 8khz.

We found theses combinaisons of parameters that "could" work :

Setting 1) P=1, J=32, D=0000, R=12
Setting 2) P=1, J=48, D=0000, R=8
Setting 3) P=1, J=26, D=0000, R=16

But when we tested theses 3 combinaisons of parameters, only the second set where doing a good job.

We could stay with the setting 2 but we feel that we should make sure that everything is allright with our settings...

Does somebody know why the settings 1 and 3 does not work?

Thanks in advance!
