AD9914 Reference Input Harmonics Requirement

I am using 3.2 GHz frequency source as a reference input for AD9914. The 3.2 GHz source is generated by picking up 4th harmonic of 800 MHz by filtering out other harmonics generated by a comb frequency generator. Now, my question is how much the nearest harmonics (@2.4 GHz and 4.0 GHz) need to be compressed down from center signal 3.2 GHz.


Thank you.
