L120-X PXI Synchronous clock cardPXI synchronous clock card

Product description

The L120-X PXI synchronous clock card supports multiple reference inputs and outputs, and can provide high-precision time information to computer systems in different combinations according to requirements. It can also provide external timing. Supports GPS, 1PPS, and TOD signals as reference source inputs, and outputs PTP, B code, TOD+1PPS signals for external timing.

This board transmits time information and timing interrupt signals to the computer through the PXI interface, achieving synchronization between computer software time and board time. Built in 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 continuing to provide more accurate time signals for the computer system, greatly improving the reliability of continuous operation of the product.
