Clock Synchronization
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).

Clock Time Regulation For IPhone
ClockMaster
ClockMaster is a clock timing software, in many ways similar to watch timegraphers, but specifically designed to work with mechanical pendulum clocks. The app analyzes the ticking sound of the escapement to determine the clock's running rate measured in Beats Per Hour (B/H). This rate is then compared to a specified Target Rate, and the Error is reported as Seconds Per Day fast or slow (±S/D).
