Is there a power supply sequence between AVDD and DRVDD of the AD9649?
You will have no problem powering up as you specified.
Please see the end of the Power and Ground Recommendations portion of the APPLICATIONS INFORMATION section of the AD9649 datasheet for the power sequencing requirements.
Thanks, Doug. Yes, I see this part, but I see only power-down sequence, but there is no power-on sequence recommendations so I ask this question.
I thought if "power off AVDD and DRVDD simultaneously, or DRVDD must be removed before AVDD" that may be I need power-on AVDD first, because I don't see text about free power-on sequence.
And sorry for my English)))
