Overview
The AD9911BCPZ, manufactured by Analog Devices Inc., is a complete direct digital synthesizer (DDS) that integrates a high-speed digital-to-analog converter (DAC) with excellent wideband and narrowband spurious-free dynamic range (SFDR). This device is designed to provide advanced signal generation capabilities, making it suitable for a variety of applications requiring precise frequency synthesis.
The AD9911BCPZ features a 32-bit frequency tuning resolution, 14-bit phase offset resolution, and 10-bit output amplitude-scaling resolution. It also includes three auxiliary DDS cores for spur reduction, multitone generation, or test-tone modulation. The device is the first DDS to incorporate SpurKiller technology and multitone generation capability, enabling the generation of up to four concurrent carriers with independent control over frequency, phase, and amplitude.
