AD Direct Digital Synthesis Modules. The circuit is taken directly from the example in the AD datasheet. and uses a MHz clock and a 40MHz output. Part Number: AD, Maunfacturer: Analog Devices, Part Family: AD, File type: PDF, Document: Datasheet – semiconductor. Introduction. This module described here is based on ADS, a CMOS, MHz, and Complete DDS. Synthesizer. The AD is a highly integrated device.

I got it working in 30 mins, though my square wave has ringing. It turned out to be a speck of something on the Arduino UNO itself. I am new with Arduino and new with DDS. Just wanted to datasheet thanks for the sketch! More power and Thank you. Continuity check revealed that there cannot be anything wrong with the module.
Please sir kindly help me to do the next part of my project. I ended up modifying slightly an Arduino sketch that was written for theputting the AD on a UNO prototype shield, and testing it in single frequency mode. Looks like yours will be the simplest.
I will greatly appreciate if anyone can confirm or otherwise what I think is happening. I had it wired and running within a matter of minutes. ADIsimDDS uses mathematical equations to model and illustrate the overall performance of the selected device. I have it transmitting using this method so far and very impressed with datasjeet inexpensive module.
My eBay DDS worked fine with your sketch.
Thanks for your testing! What AD source code to produce frequency output 20Mhz with clock in Mhz??
Here are couple of pictures: A general description, including details of the simple API and physical hook-up, appears on my blog: ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability.
I am going to add a link vatasheet direct download of the sketch. I can email you the correct code upon request:.
A couple of people above posted datxsheet links with technical docs, thank you for that, I would not have known that one sine output has a low pass filter. I am using this as an oscillator in other radios. Hi Ihab, I am not sure if this forum is still alive.
I have been playing with the Mega and want to build the antenna ad98500 project with the AD. Once an order has been placed, Analog Devices, Inc.

Thanks again for your work an Greatings from Germany Kurti. Thanks, I was able to have your sketch up and running with Energia on a Stellaris Launchpad within seconds. You code was the starting point! But dafasheet is always hard to find the simple error. Please treat me as a newbie to Arduino and programming in general. Any idea how I can turn off the AD!!!
The routine is given the required frequency Fout and finds delta Phase, the datasheet equation tells you what Fout will be for a given delta Phase:. Didn’t find what you were looking for?
Package Description The package for this IC i. I have got the sine wave successfully but am failed to get the square wave output. Comparable Parts Click to see all in Parametric Search. Feel free to improve and correct bugs. Since my last comment, I have received my AD boards and had it running on the bench in about 5 minutes!
Do you have a code where you could input a range of frequency say from khz to 30mhz? Has anyone had success outputting signals above 15 MHz? Single-Chip Direct Digital Synthesis vs. Due to environmental concerns, ADI offers many of our products in lead-free versions.

I have two of these boards and cannot get either of them to work. I am using interrupts to get the timing, and for the 80ms between the pulses I am try to send 0hz to the AD or I do a master reset. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. If not, then look for obvious stuff like no power, etc. Hi, if you want to take into account the phase between you can substitute the line: Pretty impressive little board.
I tried to write: I have been playing with the Mega and want to build the antenna analyser project with the ADquestion, will it work on 2m and 70cm bands??? Then it is the third pin from the right on the bottom row.
