ADAU1466 : external MCLK = internal PLL ???

Hello,

I use ADAU1466 with external MCLK at 24.576MHz.
Fs = 192 kHz
On this "program" :

On IN one DAC (I2S 32 bits) - On OUT 4 ADC (I2S 32 bits).
If I use "PLL clock" as "PLL CLK SRC" (with after /4 and x96), no problem, my program run (sinus on ADC in, sinus on DAC out).

If I use "MCLK pin" as "PLL CLK SRC" (with after /8 and x96), my program run but the datas on DAC out no good.

For me, in 2 cases, ADAU core run at same frequency.

PLL = 12.288 / 4 * 96 = +/- 295MHz
MCLK = 24.576 / 8 * 96 = +/- 295MHz

I don't see my error.

Thank you for your help.

Best regards,
Alexandre
