good day !
I would like to ask the following topic:
I already have 2 AD9834 with all the respective components like decoupling capacitors, resistors, etc. I follow the layout in the datasheet and I learn a lot of things.
Now, I want to control 2 AD9834 to generate two different waves independently. I would like to have 1 PCB for both, but with only 1 AD9834 I build two ground planes (DGND and AGND) with a junction at the middle of the AD9834 (just like the layout in the eval board datasheet). If I want more than 1 AD9834, what can you recommend me about where I can join the grounds ? or how can I build the grounds plane?,..
