Analog Devices Simplifies IC Selection Process with New Direct Digital Synthesis Online Evaluation Tool.

NORWOOD, Mass. -- New ADIsimDDS(TM) Tool Simplifies Task of Selecting, Evaluating and Implementing Direct Digital Synthesis (DDS) Semiconductors in Applications Ranging from Test and Measurement Equipment to Wireless and Satellite Communications

Analog Devices Inc. (NYSE: ADI), a global leader in high-performance semiconductors for signal-processing applications, today expanded its suite of online evaluation tools with the introduction of ADIsimDDS(TM). Available to designers at no charge on ADI's Web site, the ADIsimDDS tool assists users in selecting, evaluating and troubleshooting direct digital synthesis (DDS) ICs from Analog Devices. Using parametric data to mathematically model the general behavior of a selected DDS IC, it allows designers to enter the desired operating conditions, evaluate the quality of the circuit's sine wave and view the resulting harmonic images. The tool, which does not require a software download, is accessible in real-time at http://www.analog.com/ADIsimDDS.

"With ADIsimDDS, we leveraged our DDS expertise and online simulation tool leadership to take the guesswork out of the equation, and reduce design time," said David Kress, director of applications engineering at Analog Devices. "As is the case with our entire suite of ADIsim tools, designers can quickly and efficiently conduct real-time simulations, trial-test various configurations, get help with support software and troubleshoot potential problems when implementing DDS ICs in their design."

The ADIsimDDS tool allows designers to choose a DDS IC from among ADI's portfolio of products and set general parameters, such as the desired reference clock frequency, output frequency and number of reference clock multipliers required. By observing the behavior of the DDS IC within these parameters, designers obtain a real-time representation of the circuit's harmonic images and sine wave quality. To assist designers in choosing a filter, the tool is especially effective for frequency planning, which helps minimize the complexity of the filter's design. Designers who are not familiar with DDS ICs will benefit from the tool's ability to troubleshoot potential problems. For example, interactive message flags issue a series of warnings if a circuit configuration may lead to operational issues or if the circuit would degrade overall system performance. This feature helps to ensure that each circuit meets performance characteristics, greatly reducing the possibility of costly, time-consuming circuit redesigns. National Instruments' LabVIEW - a software tool for designing test, measurement and control systems - provides ADIsimDDS with a familiar graphical user interface (GUI) and processes related computational tasks.

Also included in ADI's suite of online and downloadable evaluation tools are ADIsimADC(TM), ADIsimPLL(TM), ADIsimOpAmp(TM) and ADIsimCLK(TM) - for evaluating ADCs, PLLs, operational amplifiers and clocks, respectively.
