Overview
The AD9952YSVZ-REEL7 is a 400 MSPS, 14-bit, 1.8 V CMOS Direct Digital Synthesizer (DDS) produced by Analog Devices Inc. This device is designed to provide a digitally programmable, complete high-frequency synthesizer capable of generating a frequency-agile analog output sinusoidal waveform up to 200 MHz. It utilizes advanced DDS technology coupled with an internal high-speed, high-performance DAC. The AD9952 is optimized for fast frequency hopping and fine tuning resolution, with a 32-bit frequency tuning word. The device operates over an extended industrial temperature range of −40°C to +105°C.
