Overview
The AD9910BSVZ is a high-performance Direct Digital Synthesizer (DDS) produced by Analog Devices Inc. This component integrates a 1 GSPS, 14-bit DAC and supports sample rates up to 1 GSPS, enabling the generation of frequency-agile sinusoidal waveforms at frequencies up to 400 MHz. The AD9910 employs advanced, proprietary DDS technology that reduces power consumption without compromising performance. It is controlled via a serial I/O port and includes integrated static RAM for various modulation functions.
