I am attempting to output a 10MHz Sine wave on AD9958 and control it with a profile pin. It is set up for RU/RD and P3 PWM signal controls it perfectly until the duration of P3 HIGH is less than delay for the Sine wave to turn on. When this happens, I am no longer in control of the Sine wave output. I want to control only a few 10MHz pulses so the P3 HIGH needs to be very short. Is there a setting that I have missed? Or is this chip not capable of such short pulses?
