Is the world going to DDS as best alternative? It would appear that DDS is not cost effective. What if I told you I can acheive frequency resolution of under 100 Hz with PLL Using a PIC and it's pre-scaler. I am about to embark on this project using Motorola MC145170. I will report results. I beleive the phase noise is easier to filter than frequency aliasing because of the bandwidth of noise which can be handled with a good noise limiter circuit.
