On the ADAU145x datasheet p.10 Table 8, Serial port's timing specification is described.
The test condition seems to be at 192kHz of the LRCLK and 24.576MHz of the BCLK.
The timing spec would be exactly the same if it is tested in a condition below?
LRCLK : 48 kHz
BCLK : 12.288MHz
I could not find this particular information.
Could you give us an answer for it please?
