Analog introduces ADIsimDDS

BANGALORE: Analog Devices Inc. today announced the expansion of its suite of online evaluation tools with the introduction of ADIsimDDS.

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.

“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.

Analog said in a statement that 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.

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.
