AD9912 power supply quality?

How clean do the +1.8V and +3.3V power supplies need to be for the AD9912 for noise voltage and ripple?

My application does not use the on-chip REFCLK multiplier or PLL circuits.

The DAC has an internal 1.2V reference. Does this make it insensitive to power supply quality?

Which are the most sensitive and insensitive pins for power supply quality?

Are switching supplies adequate to power the device directly, or at least partially?

Thank you.
