AD9218 Power Supplies

Hi,

I'm wondering about the timing requirements regarding the analog and digital supplies for the AD9218.

Can these supplies be initialized at different times? Must one come before the other if so?

Are there any effects of supplying two different voltages?
I'm planning on supplying the analog side, Vd, with +3V and the digital side, Vdd, with +3.3V. The +3.3V will come up a few ms after the +3V. Is this acceptable?

Thanks
