There is a google site which has nothing but lots of AD9xxx circuit images. It has an impossible
address, but you can find it through google. This is a very good source, but is all schematics.
Nonetheless, you can trace the circuit if you have the schematic.
This reipoom reference is for the version 1 board; check out the VK5TM sit for excellent
articles on how to design and build a generator based on this board. Copy the reipoom article
to your computer -- you don't know when you are going to need it (do this with everything. Hi).
Unfortunately, the later DDS boards used the version 2 AD9850. The layout is different, but the pinout
of the board is about the same. So is the software needed for the chip. There is (or was) a
description of the circuit on the web. Search for it. Sometimes it takes a bit of time to find it.
I have it. I think you can find it. No, I don't remember where I got it...
