Computer Time Card - PCIE + USB Interface

1. Time Service Communication Interface: PCI-E;
2. Time Source: Dual time sources including 4G-LTE and Beidou, with internal management on the board to ensure stable time source operation and provide accurate time;
3. Time Service Accuracy: 4G-LTE time source accuracy is 5ms, GPS/Beidou time service accuracy is 10μs;
4. Antenna: The Beidou antenna needs to be placed outdoors with the antenna sphere facing the sky; the 4G-LTE antenna can be placed indoors;
5. Timekeeping Method: Basic configuration uses a temperature-compensated crystal oscillator (TCXO), with a timekeeping accuracy error range of 500ms/day in the absence of a time source;
Optionally expandable to an oven-controlled crystal oscillator (OCXO), with a timekeeping accuracy error range of 1s/year in the absence of a time source;
6. Time Service Antenna: 4G-LTE optional lengths: 1 meter, 3 meters, and 5 meters;
Beidou optional lengths: 30 meters, 40 meters, 50 meters, and 100 meters;
7. Mean Time Between Failures (MTBF) >310,000 hours; service life >20 years, maintenance-free under normal use;
8. Supports Linux and Windows operating systems, including Kylin, Tongxin UOS, etc.;
9. Supports domestic CPUs and ARM embedded platforms;
10. Supports different chassis sizes: 1U, 2U, 3U, 4U;
11. Power Supply: PCI-E slot powered, current: 150mA;
12. Operating Temperature: 0~70℃;
13. Relative Humidity: <90% non-condensing;
14. Board Dimensions: 150x65x4mm
