Anyway, If what I am saying is correct then I will be contacting the supplier for the replacement of the module.

What AD source code to produce frequency output 20Mhz with clock in Mhz?? I had it wired and running within a matter of minutes. Hope usefull to others. Details including my translation of your code on my blog: Here are couple of pictures: What am I not understanding?

Anyone out there have any problems getting these boards to work? The encoders I used had metal bases so I slipped a xatasheet of thin insulation under them. Some of the other displays use a different controller and different Adafruit library and – not provided for in the PCB layout – require 1k series resistors in each IO lead.


If I use 5v, the frequency is right on. With a 12v DC input, the regulator does run slightly warm so I fitted it with a small heatsink. Although it claims to operate up to 40 MHz, Datsaheet found the output voltage started to drop off at about 2.

Let me ad9580 how it works out. There was a speck of dirt or metal on his Arduino, making it inoperable. I get some idea how it work now. Write me at w8mqw arrl.

Pretty impressive little board. One concern though is datashedt current it takes, I measured mA under 5V mW. Package Description The package for this IC i. Hi, Thanks for your blog.

The Sample button will be displayed if a model is available for web samples. The AD will output a square wave up to 1 MHz.

Pin Count is the number of pins, balls, or pads on the datashee. The various ranges specified are as follows:. The frequency tuning, control, and phase modulation words are loaded into the AD via a parallel byte or serial loading format.

Thanks, I was able to have your sketch up and running with Energia on a Stellaris Launchpad within seconds. Product Lifecycle Production At datashret one model within this product family is in production and available for purchase.


The model is currently being produced, and generally available for purchase and sampling. Model Package Pins Temp. Thanks for your testing!

The smallest step-rate I can use is 1 Hz. Thanks for posting your frequency programming sketch. Tried ArduinoScope but is very limiting. Your code is compiling and working great. Hi, Ron Many thanks for sharing info and code for using AD along with arduino. Hi NR8O thanks a lot for your code. The product is appropriate for new designs but newer alternatives may exist. Any idea how I can turn off the AD!!! I can send you the schematic and the code if you want. There is no way, to get any other frequence ad850 between 3.
