Direct Digital Frequency Synthesis (DDFS) techniques have fundamentally reshaped the approach to frequency generation in modern electronic systems. By employing digital methodologies such as phase ...

How does direct digital synthesis (DDS) work? There are at least three elements to DDS: a numerically controlled oscillator (NCO) with a phase modulator, a block that converts the phase information to ...

Norwood, Mass. – A single-chip device from Analog Devices Inc., the AD9858, combines a 1-Gsample/second direct digital synthesizer (DDS) with a 10-bit, 1-Gsample/s digital-to-analog converter, a 2-GHz ...

The 14-bit AD9789 and AD9739 D/A converters feature the company’s Mix-Mode super-Nyquist architecture, which supports digital synthesis of RF signals up to 3.6 GHz. The AD9789 integrates a QAM encoder ...

Specifically designed for wireless, handheld equipment, the AD9913 is the first direct-digital synthesizer to deliver a 250-MHz clock rate while consuming 50 mW of power. The device includes a 10-bit ...

Direct, indirect, analog, digital: a mixed-technology synthesizer can meet your requirements. Until recently, trade-offs have been the distinguishing characteristic of RF and microwave synthesized ...
