    Hi Tarzan,

    I like your name!

    Thank you for your interest in AD9609.

    #1 For AD9609, you can apply DRVDD and AVDD in any order.
    #2 If either AVDD or DRVDD (but not both) is applied, the part will not function (because it needs both supplies for operation), but there is no other problem I know of with applying voltage to just one supply.

    Thank you.

    Doug
