I am trying to use an AD9833 to generate a square wave. I am very new to electronics, and am having trouble understanding the MCLK pin. What hardware do I need to feed this pin? Will an NE555 do the trick?
Thanks for any help!
You will need a CMOS oscillator with a decent jitter.
The NE555 is a low speed oscillator with a poor jitter.
You can check the eval board to get a roughly idea of the components and connections for this part.
