The Design of Programmable Signal Generator Based on MSP430 and AD9854

近年来，直接频率合成技术（DDS）被广泛用于信号发生器设备中。本文介绍了一种基于AD9854的正弦信号发生器的设计方案。该设计可以实现信号的调值、频率和相位的调制。输出信号为频率0~100MHz，幅值0~5V可调。该设计结构简单、集成度高，经测试性能良好。

signal g The desi adjusted ： In recent years, The Direct Digital Synthesizer（DDS） technique is widely used in the design of enerator. The topic introduces a design scheme of sinusoidal signal generator based on AD9854. gn ： fr performance can realizes the signal modulation of value, frequency and phase. The output signal can be equency 0~100MHz, amplitude 0~5V. The design has a simple structure, high integration, good test performance.
