摘要
本文介绍了一种高性能DDS芯片 -AD985 2应用的研究结果。该合成器的DDS芯片选用AD公司最新推出的AD985 2 ,其宽带杂散优于 60dBc ,频率捷变时间小于 2 0 0ns。本文在讨论AD985 2组成与功能的基础上 ,对其在频率综合、波形合成和跳频通信系统中的应用进行了研究。
This paper presents the result research of the application of a high performance DDS chip(AD9852). The DDS chip chosen for the frequency synthesizer is AD9852 recently made by AD Inc..The broad band spurious precedes 60dBc and the time of frequency agile is less than 200 ns. Based on the research result, the application of AD9852 in the frequency synthesizer and waveform synthesis frequency hopping communication systems is investigated.
