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 ...

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 ...

The ISL5314 DDS targets wireless-communications equipment, such as base stations that link cellular telephones to the wired telephone network, satellite receivers, video-broadcast equipment, ...

Project Sponsor: Spectra Dynamics Inc. Dithered Direct Digital Synthesis Engine: It is difficult to produce a clean, tunable (phase, amplitude and frequency programmable) sinewave output signal from a ...
