PIC controlled DDS VFO

  
This is a 0 - 6 MHz DDS VFO controlled by a PIC16F84 (or `C84). The VFO is separated into two modules, the DDS module and the controller module. The PCB layout (double sided) for the DDS module is included as two Postscript files (scale 1:1). The .PS files can be copied to a Postscript capable printer such as HP LaserJet 4MP. Please note that the layout is mirrored to get the toner side of the film toward the PCB surface.

Check the text on the layout to make sure that you don`t make a mirrored PCB! There is no PCB layout for the controller. The controller is so simple, it can be built on a piece of Veroboard. Most of the components are surface mounted on the t
