PCM5102A EVM in double rate

Hello

Thank you for your support.

I had asked  my customer to evaluate PCM5102A  (PCM5102EVM-U)  for their Hi-resolutoin product in next year.

They needs 40KHz freq. responce.

So, Customer had evaluated it as;

AP2722 ( S/PDIF coax) -- PCM5102EVM-U( SRC4392-PCM5102A).

And the result was attached.

At  Fs=96KHz/double rate , as input signal frequency higher and higher, distortion is shown.

Question

Is it reasonable?

If you have THD~frequency graph at doublle rate, would you please send me?

Best Regards
