摘要
应用数字电位器MAX5477-79和单片机P89C52XBN以及选通开关CD4066B,设计了一种新型恒温晶振拐点自动配置系统.首先构建了新型晶体拐点自动配置系统的组成框图,然后介绍了系统的主要工作原理件,最后给出了系统的软件流程图和部分源代码.
A novel OCXO (oven controlled crystal oscillator) in constant temperature turnover point configuration system is designed by using digital potentiometer MAX5477-79 , microcontroller P89C52XBN and switch arrays. In this paper, the block diagram of this new OCXO turnover point configuration system is constructed firstly. Then this paper introduced how it is works of this system. Finally, the software flow process diagram and part of code of this system is given at the end of this paper.
