T800 high-performance clock server [PDF]

Summary

T800 high-performance clock server, designed specifically for high-frequency trading and other low latency network applications, is a perfect combination of highly optimized timing protocols and clock management functions. The combination of full GNSS concurrent reception, precise clock taming algorithms, and local clock can provide flexible and excellent performance, calmly responding to the constantly evolving network architecture requirements. The clock server provides multiple 1GbE (RJ-45) and 10GbE (SFP+) network ports, integrates high-precision IEEE 1588-2008 PTP packet gateway clock and Silicon Lab Si5348 ultra-low jitter network synchronizer, is compatible with SyncE standard phase and frequency synchronization, integrates jitter attenuation and clock regeneration, and supports NTP and SNTP network synchronization protocols.

The hardware of the device adopts a redundant architecture design, and the high-precision clock directly comes from the atomic clocks of various satellites in the GNSS system. By analyzing and taming the local clock source through signal analysis, the function of accurately maintaining the local clock after satellite signal loss is achieved. The device software adopts various anti-interference detection and recognition algorithms from Beidou Bangtai to detect signal anomalies caused by interference and malicious attacks on GPS signals. Unique embedded hardware design, efficient Linux operating system, and flexible expansion of various clock signal outputs. At the same time, it supports TOD, 10MHz, 1PPS, log recording, USB port upgrade and download, and dry contact alarm functions. In conjunction with Beidou Bangtai's self-developed unified network time monitoring software, it is easy to achieve network time synchronization and effective monitoring.

The T800 high-performance clock server can be widely used in fields such as government, national defense, finance, securities, insurance, mobile communication, cloud computing, e-commerce, energy and power, petroleum and petrochemical, industrial automation, intelligent transportation, security, smart cities, and the Internet of Things.
