Hi Team,,
My customer is currently looking at using TI Audio DAC for their project.
They are currently looking at PCM5121. Please see the below enquiry:
Pin 14 can be use to choose between I2S Master or I2S slave, and pin 24 can be used to select the audio format
To choose the appropriate sampling rate, do they supply different frequency to SCK to get the desired sampling rate?
The specification state that in hardware mode the SCK Rate is 128 ~ 3072 fs while the BCK rate is 64, 48 ,or 32 fs
How could they actually select the desired sampling frequency?
For example, when they supply 24.576MHz to SCK,
There are possibilities of sampling frequencies of
192KHz @ 128FS
96KHz @ 256FS
48KHZ @ 512FS
Etc.
In this case, how can they choose the desired frequency?
Thank you.
Best Regards,
Ernest
