ADF5904 Downconversion

Hello,

 

The attributes for the ADF5904 (within a parametric search on the ADI website) show that its primary function is IQ downconversion; however, isn't this just a differential output (for common-mode rejection) and not a true IQ output?

 

Furthermore, even if it is true IQ, when using the ADAR7251 to digitize, the differential signal is getting converted to a single-end output anyway.  Basically, is there anyway to get the digitized version of the true IQ signal?

 

Regards,

Will
