AVDD and DVDD power consumption in AD9951

Hello,

 

in my current design, I intend to separate the power supply of the different supply domanins in a AD9951. In order to dimension the requirements for the whole supply of the system, I need to know how much consumption I should expect in each of these parts (AVDD and DVDD, DVDD_I/O is not a problem).

 

I see that in the datasheet it is specified 171 mW for maximal single-tone operation consumption. How much of that power supplies the analog part and how much the digital part of the IC?

 

Thank you very much in advance.
