Fundamentals of Frequency Synthesis, Part 2: Please enter samples into your cart to check sample availability.

This is the date Analog Devices, Inc. Adtasheet availability may be better than production availability. The AD is datasjeet see the datasheet by a 40 datashret 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.

ADIsimDDS uses mathematical equations to model and illustrate the overall performance of the selected device. Temperature Range This is the acceptable operating range of the datasneet. Also, please note the warehouse location for the product ordered. We therefore decided to try to get away with an opamp. Anyway, we used a MHz oscillator because it was in our treasure box and the filter has a maximum attenuation at about MHz.

The programming of this “simple” dds is quite easy. For volume-specific price or delivery quotes, please contact your local Analog Devices, Inc.

The Sample button will be displayed if a model is available for web samples. This Mini-Project serves just to get a universal add-on so that our ‘free Samples’ come to life.

Once an order has been placed, Analog Devices, Inc. Didn’t find what you were looking for? Let’s get serial UT As the lowpass allows frequencies of approx. The package for this IC i.

Simple Circuit Controls Stepper Motors. At least one model within this product family is in production and available for purchase.

We do take orders for items that are not in stock, so delivery may be scheduled at a future date. 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:.

The Lowpass filter was calculated with RFSim The specific part is obsolete and no longer available. Price Rohs Orders from Analog Devices. This sinewave can be used directly as a frequency source, or internally converted to a square wave for agile-clock generator applications. This can be one of 4 stages: Because the ‘frequency tuning word’ is a 32 bit integer, when it is incremented by 1 the sine wave increases by.

Below shows a quick oscilloscope trace for a Hz wave – it looks reasonable. The various ranges specified are as follows:. Get the full sketch here.
