摘要
介绍一种在全球定位系统 (GPS)失步时 ,由高精度恒温晶振驱动一个 2 5位计数器计数 ,临时代替GPS发出时间信号的方法 ,由复杂可编程逻辑器件 (CPLD)实现 ,并利用MAXPLUSⅡ开发环境对设计结果进行功能仿真。
This paper introduces a new method of using a 25-bites counter driven by a high-precision, thermostatic crystal oscillator to temporarily replace GPS to send clock signals when GPS is desynchronized. The CPLD is adopted to realize the system, and MAX PLUS Ⅱ to simulate the functions. The system is applied in a self-designed high-speed data sampling board.
