Overview
The AD9953YSVZ is a high-performance Direct Digital Synthesizer (DDS) produced by Analog Devices Inc. This component utilizes advanced DDS technology combined with a high-speed, 14-bit Digital-to-Analog Converter (DAC) to generate frequency-agile analog output sinusoidal waveforms up to 200 MHz. The AD9953YSVZ operates at a sampling rate of up to 400 MSPS and is designed for applications requiring fast frequency hopping and fine tuning resolution, supported by a 32-bit frequency tuning word.
The device includes an integrated 1024 × 32 static RAM, enabling flexible frequency sweep capabilities in several modes. It is specified to operate over the extended industrial temperature range of –40°C to +105°C, making it suitable for a wide range of environments.
