AD9578 questions

I would greatly appreciate an answer to my two outstanding questions.

 

I have another question. I notice that the development board uses ADP7104 regulators for the AD9578. This is a low noise regulator, however the noise is much higher than the ADM7150A, which I used in a previous project to supply two off HMC832.

 

Is there any advantage in using the ADM7150A to supply the AD9578 ( at considerably higher cost)?

The answer depends upon the supply noise rejection of the AD9578, which is not specified in the data sheet.
