Re: DDS compiler

Jump to solution

yes,

 

Along with the rest of the design.  The DDS is only the numerically controlled oscillator.


To form the phase locked loop you will also need a phase-frequency comparator, a low pass filter, along with the NCO.


Often there are dividers added to perform frequency synthesis (get a different frequency out than what was used as a reference).
