Capable of generating a sinewave from low Hz (some clock scaling needed) up to about 500kHz output sweep.

Quick and dirty clock source: Not too bad for 20MHz on a breadboard: Well, it was worth a try, and my clock signal wasn't the cleanest, but I don't think it will go much faster than the internal 16MHz. But no, unfortunately it behaves exactly the same, very strange ? Tested with the same "gentle" clock signal I posted a capture of earlier, no over/under shoot, and lower in level than the AD5933 supply.Īlso had a quick go at it with a 20MHz external clock, but, while the DDS parts works fine, the internal ADC does not want to play along, unfortunately. Electronics > Projects, Designs, and Technical Stuffīuild up a simplified 2nd AD5933 to make sure the noise from external clock I'm experiencing, isn't just due to a faulty chip from all the prototyping short circuits etc.
