Posted on August 27, 2015 at 10:29 Hi Karl ,
it should be OK , if the input audio source is only from ADC .
if the clock setting of ADC is 256FS , the sample frequence will be 46.875Khz , it will not lead any audio performance changing, if the clock output jitter is very low . and due to sample frequency is not normally 48Khz , the biquad filter setting frequency will be shifted a little bit.
and to avoid jitter issue , you'd better to use external active crystal to provide 12.288Mhz MCLK to ADC and STA339BW .
Thanks ,
