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 ...
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 ...
Norwood, Mass.—Analog Devices Inc. has introduced a pair of 14-bit DACs (digital-to-analog converters) that perform direct digital synthesis for signals up to 3.6 GHz. The AD9789 and AD9739 DACs are ...
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 ...
