The amplifier I didn't use the recommended LT1819, I used ADA4927-2, may be the reason is incompatibility.
I used signal generator to input sine wave(100MHz, Vmax=1V, Vmin=0V), but I cannot get the correct waveform from the function "set up debug" of software Vivado.
Could you share to us your schematic? Also, implementation and connections would greatly help. Thank you!
these pictures are clear
I use demoboard to take signals as this picture
