AD9911集成电路（IC）的直接数字合成（DDS）规格书PDF中文资料

AD9911属于集成电路（IC）的直接数字合成（DDS）。由亚德诺半导体技术有限公司制造生产的AD9911直接数字合成（DDS）直接数字合成 (DDS) 用于由数字信号生成不同频率的模拟波形。在必须大范围扫描的无线系统中可用于频率控制。主时钟频率有 5MHz、16MHz、16.776MHz、25MHz、50MHz、75MHz、125MHz、180MHz、200MHz、250MHz、300MHz、400MHz、500MHz、1GHz、2.5GHz 和 3GHz，分辨率为 10 b、12 b 或 14 b。

GENERAL DESCRIPTION

The AD9911 is a complete direct digital synthesizer (DDS). This device includes a high speed DAC with excellent wideband and narrowband spurious-free dynamic range (SFDR) as well as three auxiliary DDS cores without assigned digital-to-analog converters (DACs). These auxiliary channels are used for spur reduction, multitone generation, or test-tone modulation.
