摘要
本文给出了一种可用于移动通信设备的高精度的时钟同步解决方案 ,外同步源来自GPS或GLONASS接收信号。CPU系统读入数字鉴相器输出相差 ,通过时间步长由小增大的方式调整恒温晶振的调谐电压 。
A clock synchronization implementation which can be used in mobile system is presented in this paper. The exterior synchronization resource is the signal receivd from GPS/GLONASS. The CPU reads the phase error data of the digital distinguisher and adjusts the input voltage of OCXO in this wayfrom a small step to a big step. As a result, a very high synchronization precision is achieved.
