Dual voltage supplies on AD9832

I have been using an AD9832 in a modem circuit (with a 5v supply). The use of a new control processor means that the digital inputs are now 3.3v. Is it possible to still use the existing 5v supply for the analogue output stage while the digital portion uses 3.3v or is the separation of the supply pins simply to aid interference/noise reduction and both parts need the same supply voltage?
