The AD digital synthesizer is a highly integrated device that uses advanced DDS technology, coupled with two internal high speed, high performance quadrature DACs to form a digitally programmable I and Q synthesizer function.

When referenced to an accurate clock source, the AD generates highly stable, frequency-phase, amplitude-programmable sine and cosine outputs that can be used as an agile LO in communications, radar, and many other applications. Retaining 16 bits for phase-to-amplitude conversion ensures excellent spurious-free dynamic range SFDR. The circuit architecture of the AD allows the generation of simultaneous quadrature output signals at frequencies up to MHz, which can be digitally tuned at a rate of up to million new frequencies per second.

The sine wave output externally filtered can be converted to a square wave by the internal comparator for agile clock generator applications. The device provides two bit phase registers and a single pin for BPSK operation. When configured with the comparator, the bit control DAC facilitates static duty cycle control in high speed clock generator applications. Chirp functionality is also included to facilitate wide bandwidth frequency sweeping applications.

This saves the user the expense and difficulty of implementing a MHz system clock source. Direct MHz clocking is also accommodated with either single-ended or differential inputs. The AD uses advanced 0. The AD is pin-for-pin compatible with the AD single-tone synthesizer. At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.

Please be aware that this product is not compatible with current Microsoft operating systems. In addition, the interface cable between computer and the evaluation board requires a parallel printer cable not available on newer computers.

For new designs, the AD and AD should be considered. ADIsimDDS uses mathematical equations to model and illustrate the overall performance of the selected device. This tool also models an estimate of the overall spectral performance, and allows the user to explore the effects of external reconstruction filters. ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability.

We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well.
