Hi,
Powering ADS54J66 for the best performance(output noise and spur level) is my problem:
1- Is JESD204B supply(1.15 V) a DGND related supply or AGND related?
2- Is 1.15 V supply necessary for best performance or i can feed 1.2 V instead? Datasheet say 1.2 V is maximum recommended value but in related Eval board used for supplying JESD204B part of IC.
3- In Eval board AGND and DGND connected together? What's your propose for the best performance?
4- Is JESD204B supply pins same as digital supply pins from the point of view of supply pollution level? Can i share IOVDD supplying regulators with AVDD suppling line and have the best performance
Regards
