摘要
由于高速DAC内部集成度的不断加大,DAC外围电路趋于简单化,用户可以根据自己的需求配置DAC内部寄存器来选择DAC的工作模式。本文在介绍AD9707的工作原理和典型电路的基础上,着重阐述了通过ARM和FPGA两种方式分别配置AD9707内部寄存器的方法,同时给出了两种配置方法基本操作的具体步骤和相应代码。
With higher degree of internal integration of high-speed DAC, the external circuit tends to be more simplified. Users can select the operating mode of DAC according to their own needs by configuration of the internal registers. After the introduction of AD9707＇s working principle and typical circuit, the paper focuses on two ways to configure the AD9707 internal registers through ARM and FPGA, and provides the steps and codes of the basic operations.
