开云体育Dozens of links, I can't find pin layout or schematic.? Every sells them no one seems to care about the data. Anyway I found 5 on eBay shipped for $55, good price for US seller! You can't buy the chip for that, these must be
counterfeit AD9850? Just pictures and code with projects. ? People all over the world making stuff with them. I use Protel, so I will wait to start layout until the boards come. Thanks Mike, WA6ISP On 7/19/2017 11:20 AM, Michael Hagen

开云体育Thanks, I found that EIM company but not as much as you got. The only thing they leave off is relative spacing from mounting holes to the pins. I will start with this info.? I can guess a
little and adjust later. I am going to compare the pictures on eBay too
with these. 73s Mike On 7/19/2017 11:47 AM, Doug W wrote:

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... john AD5YE |

I just checked the google site with all the schematics. It has images of both (all!) AD9850/51 type circuits. One can easily get the layout from there. john AD5YE -- Mike Hagen, WA6ISP 10917 Bryant Street Yucaipa, Ca. 92399 (909) 918-0058 PayPal ID "MotDog@..." Mike@... |

Just google "AD9850/51 schematics" and select the images link. Lots of them there.

Sorry I'm a bit late to this.
The pin spacing on the type 1 modules is 0.8 inch (20.32mm) across the board and the pins (as already mentioned) are 0.1 inch (2.54mm) between pins For reference, the type 2 is 1.4 inch (35.56mm) from the INSIDE row of the double row to the single row of pins. All the pins are 0.1 inch spaced, with the double row 0.1 inch apart. Terry VK5TM |
