摘要：

目的具有强大数字信号处理能力的DE2开发板在高速模拟信号处理应用中，需要结合高速AD/DA子板进行工作，而现有子板价格昂贵且采样速率有限，需要研制专用的高速AD/DA子板。方法基于DE2开发板的扩展接口进行子板设计：AD采用AD9230；DA采用AD9708；采用高级时钟芯片AD9517以满足高速AD/DA转换对高质量时钟的要求；子板使用双面板制作以降低成本。结果实验结果表明，结合DE2开发板，该子板可采样高速模拟信号，同时输出高质量模拟信号。结论研制成功的高速AD/DA子板，适合于在高速模拟信号处理中应用。

Objective The DE2 board has strong ability for digital signal processing. It works with high speed AD/DA daughter board necessarily when processing high speed analog signals. The existing daughter board is expensive and its sampling rate is not high enough，so it is needful to develop a special high speed AD/DA daughter board. Methods The daughter board was developed based on the expansion ports of the DE2 board，AD with AD9230，and DA with AD9708. AD9517 was used to satisfy the high quality clock signal in high speed conversion. The daughter board was produced by double-face board to reduce costs. Results The results indicated that the daughter board could sample high speed analog signals and output high quality analog signals with DE2. Conclusions The development of high speed AD/DA daughter board was successful and fit for the application of high speed analog signal processing.
