The datadheet has 3 7-pin headers: ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. The various ranges specified are as follows:.

Hardware, Software, Stuff I find Interesting. Synchronized Synthesizers Aid Multichannel Systems. Temperature ranges may vary by model. The performance is shown below. Sample availability may be better than production availability.

W34 must also be set. You turned it off, so they do not work. We use a crystal oscillator of MHz and do not use the internal multiplier in order to increase noise performance.

Frequently Asked Questions 1. Package Description The package for this IC i.

This is the date Analog Devices, Inc. Buy a lot of crystals: In order to power it up! As the lowpass allows frequencies of approx. Comparable Parts Click to see all in Parametric Datahseet. Below shows a quick oscilloscope trace for a Hz wave – it looks datasheft. This sinewave can be used directly as a frequency source, or internally converted to a square wave for agile-clock generator applications.

We therefore decided to try to get away with an opamp. Most orders ship within 48 hours of this date. Indicates the packing option of the model Tube, Reel, Tray, etc.

The programming of this “simple” dds is quite easy. Transit times from these sites may vary.

Let’s get serial UT Parallel or Serial Asynchronous Loading Format. We do take orders for items that are not in stock, so delivery may af9851 scheduled at a future date. Even a second one can be plugged on it, as the user may assemble R7 OR R9 to distinguish between them.

This Mini-Project serves just to get a universal add-on so that our ‘free Samples’ come to life.

The AD contains a unique X6 reference clock multiplier circuit that obviates the need for a high-speed reference oscillator. For more information about lead-free parts, please consult our Pb Lead free information page. The package for this IC i.

As this board is intended to work in the MHz-range, where monolithic amplifiers are demanding unpractical large inductors for biasing. That’s it for now – I might spend some more time looking at the output waveforms if I can find a use for the device.

Product Lifecycle Production At least one model within this product family is in production and available for purchase. Please Select a Region. Model The model number is a specific version of a generic that can be purchased or sampled. Measure replacement data Crystal Filter Design 2: For volume-specific price or delivery quotes, please contact your local Analog Devices, Inc.

In case you use the internal clock-multiplier, W32 Bit 0 of Word 0 must be set. This tool also models an estimate of the overall spectral performance, and allows the user to explore the effects of external reconstruction filters.

At least one model within this product family is in production and available for purchase.

Homebrew DDS Generator (with AD)

The Sample button will be displayed if a model is available for web samples. Also, please note the warehouse location for the product ordered. Due to environmental concerns, ADI offers many of our products in lead-free versions. For the crystal oscillator a separate voltage regulator is available, in order to generate different voltages necessary for different oscillator types. The AD is controlled see the datasheet by a 40 bit control word consisting of a 32 bit ‘frequency tuning word’ and an 8 bit ‘control’ word comprising of 5 bits of phase angle so that multiple ADs can be controlled from the same clock outputing the same sine wave shifted by a different amount.

Pin Count Pin Count is the number of pins, balls, or pads on the device. The model has not been released to general production, but samples may be available. I found the reset pin could be left tied low in these simple tests but i’d do an explicit hardware reset pulse in an application.
