I need to be able to generate a square wave with accurate 50/50 duty cycle at 1MHz and 5MHZ. I would also like to be able to control the amplitude of the output via DAC or something.

Can you suggest a simple circuit to do this.Component count is a concern.

I currently have an AD9834 eval board. One issue is that the duty cycle is off a bit. Total period is right. I also can't control the amplitude.
