Development of modern digital synchronization modules at BINP

Modern digital synchronization system for big physical facilities is developed at BINP. It allows synchronizing the spatially distributed control devices with an accuracy of ±125 ps and low jitter (< 100 ps). Accurate time distribution and delay compensation is provided, as well as an ability to react to external events with a determined latency. Two modules are used in this subsystem: S-Timer and LTimer. S-Timer provides a synchronized 250 MHz clock signal with embedded events data through the optical link to nine L-Timers or S-Timers. L-Timer decodes the signal from the optical link and provides synchronization pulses to final control devices.
