摘要
介绍C8051F007的特点和微机补偿晶体振荡器的构成,以及各部分硬件电路的设计和工作原理,另外介绍了一种用于数据处理的曲线拟和方法。通过实验得到各变量之间的函数关系,根据各变量关系使漂移的晶体振荡器恢复到标定的频率值。基于C8051F007的微机温度补偿晶体振荡器,利用其自身带有A/D和D/A改善了传统的微机补偿晶体振荡器在体积和精度上存在的不足,使其更具市场竞争力。
The characteristics of C8051F007 and the constitutions of MCXO with the design and working theory of each hardware circuit are introduced. With experiments, the functional relationship between the variables could be got. According to the relationship, we can renew the changeable crystal surge＇s frequency to original value. In addition, a kind of curve fitting method which is used to process data, based on C8051F007 of MCXO improve traditional MCXO on volume precision though A/D and D/A of themselves. The research makes it more competitive in market.
