Hi everybody,

 

I'm new using DDS ICs. I have to use an AD9910 for a project.

 

I saw in the datasheet that, there are 4 working modes. but each mode is too advanced for my use. In a first time, i would like to set a fixed frequency in output with a fixed amplitude.

 

Then i want only change the frquency. So can I directly configure the FTW registrer to change frequency without use "sigle tone mode", "rampe mode", "Parallele mode", "ram mode".

 

thanks in advance for your help and sory for my bad english
