LP-100 PCIe Timing CardLP-100,PCIe,Timing,Card,The,LP

The LP-100 PCIe timing card can be used to provide high-precision time information for computer systems. This board uses a receiver or PTP signal as a time reference, and transmits time information and timing interrupt signals to the computer through the PCIe interface, achieving synchronization between computer software time and board time. When a reference source is abnormal, it can automatically switch to other valid reference sources; Even if all reference time sources are cut off, the high stability crystal oscillator inside the board can still maintain a certain time precision and provide more accurate time signals for a certain period of time, greatly improving the continuous operation of the product within the range, thus continuing to provide reliability for the continuous operation of the computer system. This board is widely used in industries such as scientific research metrology, communication, power, transportation, and industrial automation.
