Clock Synchronization
Analog Devices 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 relying 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 synchronizing systems throughout both computer networks and local area networks (LAN).
