Full source of a SPI arduino sketch is here. 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. The Sample button will be displayed if a model is available for web samples.

AD Datasheet and Product Info | Analog Devices

Product Lifecycle Ae9851 At least one model within this product family is in production and available for purchase. It is important to note the scheduled dock date on the order entry screen. Buy a lot of crystals: Model The model number is a specific version of a generic that can be purchased or sampled.

As this board is intended to work in dayasheet MHz-range, where monolithic amplifiers are demanding unpractical large inductors for biasing. Also, please note the warehouse location for the product ordered.

Model Package Pins Temp. Please Select a Language. The Circuit diagram included on the ebay auction had no resemblance to the device I got, but it seems the design is the same or similar to most of the barebone AD boards on ebay – just the chip, 30MHz crystal, header pins, bypass caps, and a low pass filter.

Synchronized Synthesizers Aid Multichannel Systems. International prices may differ due to local duties, taxes, fees and exchange rates.

Parallel or Serial Asynchronous Loading Format. Please consult datashet datasheet for more dataxheet. Due to environmental concerns, ADI offers many of our products in lead-free versions.

Courtesy of Analog Devices. Sample availability may be better than production availability. 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. The model is currently being produced, and generally available for purchase and sampling.

W34 must also be set. Even a second one can be plugged on it, as the user may assemble R7 OR R9 to distinguish between them. The programming of this “simple” dds is quite easy.

The package for this IC i. At least one model within this product family is in production and available for purchase. The Year of the Waveform Generator. The device has 3 7-pin headers: Pouring this knowledge into software, our bitstream, should look like the picture below. Rectification Power Supply Designer: In datwsheet to power it up!

The Lowpass filter was calculated with RFSim Temperature ranges may vary by model.

The model has not been released to general production, but samples may be available. In serial mode the chip can be controlled with only 3 pins plus VCC and GNDbasically a bit from the control word is written to the DATA pin, W CLK is pulsed high until all 40 bits have been sent and then FQ UD is pulsed high to transfer the 40 bits from a buffer to the control register as shown below from the datasheet:.

Anyway, we used a MHz oscillator because it was in our treasure box and the filter has a datasbeet attenuation at about MHz. For detailed drawings and chemical composition please consult our Package Site. Note, that the Datasehet is transmitted first! For more information about lead-free parts, please consult our Pb Lead free information page. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well.

The AD is controlled see the datasheet by a 40 bit control word consisting datssheet 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.

If a model is not available for web samples, look for notes on the product page that indicate how to request samples or Contact ADI. In case you use the internal clock-multiplier, Ad98511 Bit 0 of Word 0 must be set. For volume-specific price or delivery quotes, please contact your local Analog Devices, Inc.

This is the dataxheet operating range of dztasheet device. Select the purchase button to display inventory availability and online purchase options. When using version 1. An Evaluation Board is a board engineered to show the performance of the model, the part is included on the board. For the crystal oscillator a separate voltage regulator is available, in order to generate different voltages necessary for different oscillator types. As the lowpass allows frequencies of approx.
