Hi,

an NCO generates any frequency below clk/2 on the fly by changing the tuning word value.

The tuning word value depends on your clock frequency and tone as well as the width of tuning word and there is a formula for that.

The easiest way is this:

When you enter your NCO settings you will find entry for sampling frequency(your effective clock) and a given tone in Hz ...etc then the GUI will get you the tuning word value.
