Hi, the MCLK=37.5M, the audio raw data frequency is 20k, so I think the desired sampling rate should lager than 20k, for example 48K.
At this moment, I have changed the DOSR to 128, N = 3, M = 5, P = 3, R = 1, J.D = 7.3287, so that the DAC_fs = 48k, but it still work hard. what can i do now? thanks.
