Hello.
I finally received my AD9833 module.
I read about serial interfacing that it uses and tried to find pinouts.
I bought a cheap module and it came with no documentation.
The circuit of the module is cutoff. Is "REF" pin the same as a "COMP" pin?

What is an out pin? Signal?
There is a round threaded connector for output. Is this the F connector?
I am planning to use this circuit with an amplifier.
What kind of amplifier I should use and how I should connect it to the circuit?
I am reading all around SPI and I find no example in Arduino C of how to interface AD9833.

The datasheet is not telling me anything about the clock polarity or clock phase.
What do I do? It is so difficult to make this board work. I am afraid that I will burn it.
(I have seen this: Interfacing DDS chip and Arduino/Atmega168 - Syntax & Programs - Arduino Forum)
I read the datasheet for AD9833 but what C code do I use to address it?
Thank you.
