The time synchronization server takes GPS signal as the time source, and at the same time, it can choose BeiDou, B code, CDMA, atomic clock and other time sources. The time synchronization server product adopts full modular structure design, which not only realizes the full compatibility of boards, but also provides rich signal interface resources and open special interface design platform with excellent compatibility ability. It can provide multiple NTP/SNTP signals, PTP signals, pulse signals (1PPS/M/H, null contact, differential, TTL, 24V/110V/220V active, optical), IRIG-B signals (TTL, 422, AC, optical), DCF77 signals, and time telegrams (RS232, RS422/485, optical), which can satisfy the time synchronization interface requirements of different devices. It can meet the requirements of timing interface of different equipments, and is widely used in electric power, finance, communication, transportation, radio and television, security, petrochemical, metallurgy, water conservancy, national defense, medical care, education, government agencies, IT and other fields. The time synchronization server equipment is produced by surface mount technology and controlled by high-speed chip, featuring high precision, good stability, strong functions, no accumulation of errors, not subject to environmental conditions such as geographical climate, high cost-effective, easy to operate, maintenance-free, etc., and is suitable for unattended operation.
