In order to meet the resolution requirement of hundreds of microseconds, microsecond global clock synchronization must be achieved in Sequence of Event (SOE) system.
为了满足事件顺序记录(SOE)系统数百微秒级分辨率的要求，系统必须实现精确到微秒级的全局时钟同步。

The clock signal provided by Global Positioning System(GPS)is widely used in electric power system for relay protection, SOE (Sequence of Events), fault locating, synchronous sampling and so on.
GPS同步时钟信号已在电力系统的继电保护、事件顺序记录、故障测距、同步采样等诸多领域获得重要运用。

This circuit is implemented on a monolithic chip, which is comprised of a period time sampling unit, a peri-od distanee preset unit, an arithmetic unit, a clock and time sequence unit.
