基于实现简单高效地产生MSK调制信号的目的,文中系统性地阐述了AD9854的工作原理、机制,探讨了采用AD9854产生MSK调制信号相比传统方法的优越性。同时详细介绍了通过FPGA配置AD9854的方法 ,描述了硬件平台的搭建并且列出了所有需配置寄存器列表。将产生的MSK调制信号连接至示波器和频谱仪,分别观测该方法产生的MSK信号。结果表明,输出电平达到-14 d Bm,无杂散动态范围达到了60 d B,从而验证了该法产生MSK信号的正确性和优越性。

Based on the purposes of generating MSK signals efficiently, the article systematically describes the working principle and mechanisms of the AD9854, and explores advantages of using the AD9854 to generate MSK signals compared to traditional methods. The article depicts details of the method by employing FPGA to configurate AD9854, which describes the hardware platform and lists all registers that should be configurated. By observing the MSK signal from the oscilloscope and spectrum analyzer, the result shows that output level reaches -14 dBm, spurious-free dynamic ranges up to 60dB, hence, verifies that the method to generate MSK signal proposed in this article is correct and superior.
