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
