PCM5102A: Could you tell me whether there is issue or not when power on / power off time was difference for AVDD&CPVDD and DVDD?

Hi Expert.

This is Koki Tsushima.

My customer wants to know whether there is issue or not when power on / power off time was difference for AVDD&CPVDD and DVDD for PCM5102A.

Customer is currently using PCM5102A with AVDD&CPVDD from same power supply and 1.8V DVDD from other power supply.

Customer and I are understanding that there are no mentioned when power on / power off time was difference for AVDD&CPVDD and DVDD for PCM5102A.

Is this understanding correct?

 - If so, are there any issues if power on / power off time was difference for AVDD&CPVDD and DVDD?

If not, what will be expected to be happened?

 Customer said that he can accept if there is pop noise etc. because he designed circuit in order to mute after this PCM5102A.

 And he said that he can power ON reset, therefore, it is OK if IC will not break.

Thank you.
