AD9388A power sequence

Hello there,


We have got a new board equipped with AD9388A, where the power sequence is unfortunatelly different from the datasheet recommendations. We've tested the board and everything seems to be functional, there are no side effects as far as we can see. Should we count with any short- or long-term effect, when the recommended power sequence is not followed? In our cases the DVDDIO reaches the nominal 3.3V level before the DVDD could be stabilized on 1.8V.


Thank you in advance for your advice
