IEEE1588 Synchronous Technology Assists the Informationizati

The professional Beidou time and frequency solution supplier, Beidou Bangtai, has recently completed the synchronization of the PTPv2 (IEEE1588-2008) protocol clock network for a certain military department's information construction, providing 30 nanosecond synchronization accuracy for key equipment.

With the continuous development of information warfare, the reaction speed of the battlefield will continue to accelerate, and "real-time" may truly emerge. The potential emergence of network centric warfare in the future will further increase the reaction speed of the war.

T504-PTP PCIe PTP slave clock card can be used to provide high-precision time information for computer systems. The board can use various time information such as PTP, B code, or 1PPS+TOD as the time reference, and transmit time information or timed interrupt signals to the computer through the PCIe interface to achieve synchronization between the computer software and hardware system time and the board's time reference. When a reference time source is abnormal, it can automatically switch to another reference time source; Even if all reference time sources are cut off, the highly stable crystal oscillator inside the board can still maintain high-precision continuous operation for a certain period of time, thereby continuing to provide accurate time signals for the computer system, greatly improving the reliability of product continuous operation. In addition to providing time information to the computer through the PCIe port, the board can also output time information externally through the onboard output port. For example, the SCSI-50 interface can output B code time information, 1PPS+TOD time information; The gigabit network port supports PTP (1588V2) protocol transmission, which can output time information outward as the main clock and receive time information as the slave clock. The biggest advantage of the product is its flexible input and output configuration. Users can set different time signal sources according to their needs and output various required signals according to application requirements. It can be used as a single board card or as a time unified system with multiple interconnected cards. Currently, it has been widely used in fields such as aviation, communication, power, finance, security monitoring, railway transportation, IT systems, and industrial control.
