摘　　要：介绍利用VDSL2网络集成芯片设计的多信号发生器,该网络芯片集成有ARM处理器,两级低噪声放大器,三级低通滤波器,数字信号处理器以及14位DAC。该系统充分利用该芯片高集成的特点,设计了具有嵌入式的微型化多信号发生器。该发生器利用Matlab用户界面实现了输出频率从0.01 Hz^20 MHz的各种常规波形和用户自定义的任意波形。该系统成本低,效果佳,体积小,已经应用于实验室的各种电子应用技术实验中。The multi-signal generator designed with VDSL2 （very-high-bit-rate digital subscriber line） SoC （system-on-chip）is presented in this paper. ARM CPU,2-stage LNA,3rd-order LPF,digital signal processor and 14-bit DAC are all inte-grated in the SoC. This microminiaturization multi-signal generator has characteristics of embedded system,which makes full use of highly-integrated performance of SoC. The general waveforms and user-defined arbitrary waveforms of 0.01 Hz^20 MHz output frequency is realized with Matlab GUI. This signal generator has the characteristics of low cost,high performance and small size,which has been already used in various electronic application experiments in laboratory.
