Hi to all.
I am running some tests with the ADAU1701 and i am little bit confused
My master clock is 25MHz and it comes from an CM6631A configured to 24bit 96Khz.
PLL mode is set to 256xFs.
The CM6631A also provide 2 channel audio thru I2S.
The ADAU1701 sampling rate is set to 92KHz and DSP core to 2x ... everything is working fine ... i have good sound from both I2S and ADCs.
The strange thing is that the ADAU1701 keeps working also when i set the sampling rate to 48KHz and DSP core to 1x ... good sound from both I2S and ADCs.
Is that normal, and why ?
Thanks in advance
