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.

Most orders ship within 48 hours of this date. You could just jumper to the main Arduino board. It is all working fine. You should now be able to copy and past the code and it will compile correctly. I had to install a plug-in so it would display correctly. At least one model within this product family is in production and available for purchase.
On a 20M DC receiver: Or are there any comparable modules at a slightly higher price but better quality? Have you considered making this an audio sweep generator?
Thanks a ton for taking the time. We do take orders for items that are not in stock, so delivery may be scheduled at a future date.
The square wave is around 5 volts peak-to-peak. Synchronized Synthesizers Aid Multichannel Systems.

Good luck with the DDS module. Note that I have changed the four Arduino data port freq control pins of the AD module so that the 8 keypad ports could all be contiguous:.
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??? Thanks for your blog.
The parallel load format consists of five iterative loads of an 8-bit control word byte. It was mentioned that the pots are touchy. Now on to finish VFO! I had it wired and running within a matter of minutes. Ad980 make the matters worse, I lost my old TekA scope also. Parallel Byte or Serial Loading Format. Thanks for your testing!
What I need it a steprate from abt. The AD also contains a high speed comparator that can be configured to accept the externally filtered output of the DAC to generate a low jitter square wave output.

Connected up just like instructed and uploaded the sketch. I hooked up the chip and got it working using the code you provided.
Serial loading is accomplished via a bit serial data stream on a single pin. HamRadio guys used this board apparently with good luck.
Indicates the packing option of the model Tube, Reel, Tray, etc. Put a scope probe on the third pin. ADIsimDDS uses mathematical equations to model and illustrate the overall performance of the selected device. N8RO did an excellent job. I have tried two now and neither are working. Can I connect the module to the COM port?
Any idea how I can datadheet off the AD!!! Next I thought, what if my unit left the factory not setting R13 Trim Pot properly duty-cycle. May you can explain the way, how to calculate the frequency on the output on my Ad98500 Thanks for posting your experience and your code.
This sine wave can be used directly as a frequency source or converted to a square wave for agile-clock generator applications. I get some very bad harmonics and ugly looking sine waves the higher the output frequency, starting around 15 MHz.

I am using this as an oscillator in other radios. Once an order has been placed, Analog Devices, Inc. Many of these are sensitive datqsheet the rotation of the blue pot. Thanks, I was able to have your sketch up and running with Energia on a Stellaris Launchpad within seconds. International prices may differ due to local duties, taxes, fees and exchange rates.
I got the datasheeet problem with the program and the analog website. I found more data online, and the seller could not provide support. Tried ArduinoScope but is very limiting. Very pleased I found your site which is now bookmarked.
