AD9522

Hi,

 

I'm currently attempting to use the AD9522 Eval to clock my AD9914 Eval. I am using the internal VCO of the AD9522 Eval, but when I externally measure the output signal of my AD9522 I see a different frequency from what the evaluation GUI is telling me it is outputting. When I change the value in the REF1 box, the value that the GUI tells me that it is outputting changes, but nothing actually happens to the output signal.

 

Do I fundamentally misunderstand how the chip determines it's own output, or is there just some simple mistake I am making?

 

Thanks!
