I have AD9164 and Eval Board. Do In need to operate in 2X NRZ mode to obtain 3.5GHz frequency? What will be the power level of that frequency? and If I need a coarse switching of the frequency from 0.1GHz till 4GHz Should I shift from baseband mode to 2XNRZ mode? If so what is the switching time taken between modes? And what is maximum difference in amplitudes when I switch to different modes?
