I would like to use DDS to build a waveform generator for my new design. The output signal range is 2kHz to 500kHz, pulse width range 1~20ns, rise time <=1ns amplitude can be modulated (arbitrary shape). I found AD9102 that looks interesting, but this part is limit at 180MHz. Do you have any parts that you can recommend for my application?
