digitally compensated crystal oscillator 数字补偿晶体振荡器;
The designed DCXO adopts Pierce architecture. The frequency drift correction is done by using a 6-bit automatic frequency control ( AFC) signal generated by the feedback correction loop between the oscillator and the base band. The long term stable frequency output has been obtained.
所设计的数控晶体振荡器采用Pierce结构,利用基带与振荡器的反馈环路产生的6位自动频率控制信号,对振荡器的频率漂移进行校准,能得到长期稳定的频率输出。
