Overview
The AD9952YSVZ, produced by Analog Devices Inc., is a high-performance direct digital synthesizer (DDS) that integrates advanced DDS technology with a 14-bit digital-to-analog converter (DAC). This device is capable of generating frequency-agile analog output sinusoidal waveforms up to 200 MHz, making it ideal for applications requiring fast frequency hopping and fine tuning resolution. The AD9952 operates with a 32-bit frequency tuning word and supports multichip synchronization, phase modulation, and an internal oscillator that can be driven by a single crystal. It is designed to operate over an extended industrial temperature range of −40°C to +105°C.
