hello.i just made a frequncy generator with AD9850 and i want to have and a pwm signal which i can controll it with a rotary potentiometer. how can i do that?

I haven't used the part but it seems you clock-in the frequency and phase data either serially or in parallel bursts. So I'd imagine you'd want/need a microcontroller or similar to control it with. Then I guess you can use a potentiometer as interface if you really want, although most would probably choose a rotary encoder at this stage.
