Serial Port Correct Settings

Dear Dave, Team,

We are interfacing A2B with our ADAU1466 Evaluation Board .

The flow is as follows A2B Main (running TDM16 @ 48kHz) -> A2B Sub Node(running TDM4 @ 192kHz {Increased Data Rate Feature)} -> ADAU1466 Serial Input Port 2

The following are the register settings I have

With the above settings I receive the 16 channels data packed in TDM 4 in correct order.

However i am not certain if the BCLK polarity should be left negative in the Serial Port of ADAU1466 . So, when I did try to change the BCLK polarity to align with the A2B Sub Node setting I invited trouble and the Channel order went haphazardly haywire .

Now I did probe the A2B Sub Node and found that the TDM data Slots are in correct order as expected.

So it seems that the problem is occurring when I am getting the TDM data from the Sub Node to the Serial Port in ADAU1466 .

Here is the project file .

Please also let me know your thoughts on this.

Regards,
Hermione
