LP-120 PCI GNSS Timing CardStandard time clock card

Product description

The LP-120 PCIGPS Beidou clock card supports GPSBD multi-mode receiver, taming local constant temperature crystal oscillator, providing accurate time information for computers, and can also be used for external timing, supporting timing signals such as IEEE1588, B code, 1PPS, and TOD.

This board transmits time information and timed interrupt signals to the computer through the PCI interface, achieving synchronization between computer software time and board time.

The GPS Beidou synchronous clock is equipped with a high-temperature constant temperature crystal oscillator. 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 providing more accurate time signals for the computer system and greatly improving the reliability of continuous operation of the product.
