What is the maximum voltage difference allowed between AVDD and DVDD with an AD9850?
I would like to use DVDD = 3.3V, AVDD = 5V.
Is there a list of which pins are referenced to AGND and which are referenced to DGND?
Final question - is it worth the effort to use seperate supplies?
I'm using this in a 30-88MHz radio and the current design uses a single supply for the 9850.
