Homebrew DDS Generator (with AD9851)

This Mini-Project served just to get a universal add-on so that our 'free Samples' come to life. We use a crystal oscillator of 120 MHz ( and do not use the internal multiplier ) in order to increase noise performance. It is possible to use an external Ref.-Clk as well. The board uses a single +12V Supply, as it will generate +5V (for AD9851) and +2.5V (for crystal oscillator) itself. The output of the AD9851 is lowpass-filtered and amplified with a Gali-4 (from MCL).
