DVDD voltage in AD9951-9954

Hallo,

 

can I power the DVDD pins with 3.3V in this DDS? I am not very aware of the possible consequences of doing such thing, as the datasheet specifies that they should be powered at 1.8V.

 

I am working with a design which has that "failure" and it does not work... what I would like to isolate is the fact that this can be the critic failure or if it is the case that more things than this can be bad designed.

 

Thank you in advance.
