Overview
The AD9858BSV, produced by Analog Devices Inc., is a high-performance Direct Digital Synthesizer (DDS) that integrates advanced DDS technology with a high-speed, high-performance 10-bit Digital-to-Analog Converter (DAC). This component is designed to generate a frequency-agile analog output sine wave up to 400 MHz, making it suitable for a wide range of high-frequency applications. The AD9858BSV operates with an internal clock speed of up to 1 GSPS and can accept an external reference clock as high as 2 GHz, thanks to its divide-by-2 feature. It is powered by a 3.3 V supply and is specified to operate over the extended industrial temperature range of –40°C to +85°C.
