摘　　要：采用时分多址协议的光网络中, 突发同步是一项关键技术, 一般采用基于多相时钟的关键字检测法。基于对异步传输模式棗无源光网络的研究,提出了对AS1773协议的突发同步设计。采用了高速现场可编程门阵列的方式实现20 Mbps突发同步器,简化了电路的设计,相对于传统的专用集成电路设计方案设计方案,具有开发成本低、开发周期短的优点。This paper Burst mode synchronization is a key techno logy in passive optical network that utilizes time division multi access (TDMA) with single mode fiber. For the clock recovery in burst mode transmission, a burst mode synchronizer using keyword detection based on multiphase clock is usually used. In this article, based on research in asynchronous transfer moder-passive optical network, author described a method to design burst synchronizer in AS1773 protocol. This synchronizer is implemented by field programmable gate array, which can achieve high performance with low cost, short developing period.
