ADAU1467 TDM16 problem
Hello, I'm working on a custom A2B subordinate board. The subordinate transceiver get 16 streams from A2B network and generates a TDM16 towards a ADAU1467 with the input serial port 1 configured like this:
I saw the signals with the oscilloscope and they are ok ok: MCLK and BCLK = 24.576MHz, LRCLK = 48KHz.
Now, from ADAU1467 output (configured simply in passthought) I have the first 8 slot ok, but the second 8 signals are not good.
Any ideas that can cause this effect? Thank you.

Hello Marcosilenzi,
It would be helpful if you could share your project.

Could you please tell me, what do you means by 'not good'? Is it distorted? or channels are misaligned?
How are you checking this? A scope shot of what you observed would be helpful.
If you are sending the signal from output port to other chips for measurement, make sure the clock polarities are correct between the two chips.
Regards,
Harish
