LP-120-B PCIe B-Code CardB码时钟卡

Product description

The LP-120-B PCIe B-code clock card can be used to provide high-precision time information for computer systems. This board uses B-code time information as a time reference and transmits time information and timing interrupt signals to the computer through PCIe interface, achieving synchronization between computer software time and board time.

Supports two B-code signal inputs, and can automatically switch to another B-code source when one B-code source is abnormal; Even if all reference time sources are cut off, the high stability crystal oscillator inside the board can still maintain continuous operation within a certain time accuracy range, thus continuing to provide more accurate time signals for the computer system, greatly improving the reliability of the product's continuous operation.

The GPS Beidou synchronous clock board is widely used in industries such as scientific research and measurement, communication, power, transportation, and industrial automation.
