I would like to know the power supply sequence of DVDD, AVDD and DVDD_I/O for AD9959.
Does AD9959 have power-up and power-down sequence in DVDD, AVDD and DVDD_I/O ?
There isn't a recommended power up or power down sequence that is specified by the data sheet. It follows that you can safely power up the device in any sequence you prescribe. The only concern is to ensure that the supply ratings would not exceed the maximum allowable during power up.
