This is a DDS breakout board (Analog Devices AD9958 DDS chip) that I designed.  I haven’t soldered the components to the board as I accidentally broke 2 pins off of the AD9958 chip as I was desoldering it from another board to put it on this board.  Will need to get another chip from digikey or maybe a sample from Analog Devices.  Here are the schematics and pcb files along with some of the pictures of the project. The schematics and pcb files (gEDA) are included here:  ad9958-bo1.sch  ad9958-bo2.sch  ad9958-bo.pcb

Screen shots of the schematics:  ad9958-bo1.sch   ad9958-bo2.sch

Here are some of the etched boards that I made of this breakout board using the toner transfer method with CuCl etchant.
