Product Introduction

Overview

The AD9912ABCPZ-REEL7 is a high-performance direct digital synthesizer (DDS) produced by Analog Devices Inc. This component integrates a 14-bit digital-to-analog converter (DAC) and operates at an internal clock speed of 1 GSPS, enabling output frequencies up to 400 MHz. The AD9912 features a 48-bit frequency tuning word, allowing for fine frequency resolution of 4 Hz. It also includes an on-chip low noise phase-locked loop (PLL) and supports flexible system clock inputs, making it versatile for various applications.
