时钟同步

Analog Devices Clock synchronizers are designed for wired networking applications, providing the clock redundancy functionality needed to maximize system uptime. Our technology supports clock synchronization with common standards, including 1 pulse per second (PPS) output signal from a GPS receiver. GPS signals are broadly available and utilize an extremely stable atomic clock as its time base, but they are often noisy. Systems rely on the IEEE1588 timing protocol to establish synchronous communications across the wired network, including synchronous Ethernet and synchronous digital hierarchy (SDH) to optical transport network (OTN) mapping/demapping. The IEEE1588 protocol has emerged as the preferred method for Clock synchronizing systems throughout both computer networks and local area networks (LAN).
ADI公司同步器设计用于有线网络应用,提供最大化系统正常运行时间所需的时钟冗余功能。我们的技术支持通用标准的时钟同步,包括:

  • GPS接收器所提供的1秒脉冲(PPS)输出信号。GPS信号普遍可用并利用非常稳定的原子时钟作为其时基,但通常较为嘈杂。

  • 系统依靠IEEE1588时序协议建立有线网络中的同步通信,包括同步以太网和同步数字体系(SDH)至光传输网络(OTN)映射/解映射。IEEE1588协议已成为在整个计算机网络和局域网(LAN)中同步系统的首选方法。
