RF synthesis is a critical function in today's electronic communications systems. Two of the technologies used for RF synthesis are phase locked loop (PLL) and direct digital synthesis (DDS). Each has ...

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 ...

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 ...

Traditionally, portable and embedded systems designers looking to add frequency synthesis capability choose to go with phase-locked-loops (PLLs) or implement it on their field-programmable gate arrays ...

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 ...

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 ...
