Received AD9833 - Direct Digital Synthesizer!

We Have some Reference! Managed to pull ~4.5Mhz on VICHY VC99.
The signal was fed directly to VC99(not terminated), while in audible range it was also powering 64Ω headphones (32Ω+32Ω connected in series)

TODO: adding amplifier and digital pots for AREF and amplified signal attenuation, phase shifting. This will be remotely controllable & programmable DDS. More details later - maybe I should create separate sub-projects?

Code borrowed form http://www.vwlowen.co.uk/arduino/AD9833-waveform-generator/AD9833-waveform-generator.htm

AD9833: 0 MHz to 12.5 MHz output frequency range; VOUT Maximum 0.65V

VC99: Frequency 10Hz - 60mHz; Input sensitivity: 0.7V
