一种新型的微机补偿晶体振荡器及开发系统

A New Type of MCXO and its Test System

提出了一种新型的以微处理器为核心的AT切温度补偿晶体振荡器 (MCXO)的设计思想 ,说明了其开发系统的原理 ,给出了最后的实验结果。使用该开发系统得到的这种振荡器可以工作在 - 40℃～ 85℃的环境内 ,频率—温度稳定性≤± 5× 10 - 7。

This paper presents the design idea of a new type of MCXO used an AT-cut crystal resonator which is based on microprocessor. The principle of its test system and its final results are also given in this paper. The operation temperature range of this type of MCXO obtained by its test system is -40℃～85℃ and ≤±5×10 -7 frequency-temperature stability is expected value.
