, ok , I'm back. Tron9000, I have the data sheets for both, you are correct, it does go to 1Mhz in the specs, I could of sworn I read it only went to 200Khz but I was obviously wrong.
DDS is something I haven't given any thought too. Mainly because I have these IC's and a couple of pics and my brain just thought, hmm, it could be cheap and easy to do. I will certainly have a look at that avenue.
