10MHz DDS Sine/Square Function Generator based on the AD9835

7

Here is a 10MHz function generator with full details on how to build it.

“An extremely simple and low cost Sine/Square wave generator based on the Analog Devices AD9835 Direct Digital Synthesis (DDS) Generator chip. The frequency can be set for any frequency from 1Hz to 10MHz in 1Hz resolution steps! All this with three push buttons and a novel “sliding window” LED display. The controller chip is a Microchip PIC16F628. There is no wiring, and the PCB fits into a standard UB3 Jiffy Box.”

  1. Is that “Silicon Chip”, as in the Australian Electronics magazine?


  2. look very much like a Silicon Chip project i wonder what month this is from as i haven’t seen it but it looks like one of there new layout styles


  4. Of course, they engulfed EA didn’t they?
    Always thought EA was the stronger magazine of the two, oh well.


  5. hum on the pcb it says 1/10/02 if it was a ea project would it not of said ea instead of siliconchip?
