Cesium Atomic Clock (Cs Clock)

• ArctiTech

TA1000 Laser Pumped Small Cesium Atomic Clock: The volume is equivalent to that of a computer host, the frequency accuracy is 1E-12, and the 1-second stability is 1.2E-11. It has passed the acceptance of the Ministry of Science and Technology and is used in Arctic scientific research.

TA1200 Enhanced Cesium Clock: The civilian version has a frequency stability of 8.5E-14 (100,000 seconds), a lifespan of ≥120,000 hours, and supports telecommunications and power synchronization networks.

• Microchip

5071B Cesium Atomic Clock: 3U rack-mounted design, frequency accuracy of 5E-13, can maintain 100 ns accuracy for 2 months when GNSS fails, suitable for 5G core network and military communications.

Comparison: ArctiTech TA1000 has made significant breakthroughs in miniaturization and domestic substitution, while Microchip 5071B is superior in high reliability and long-term autonomous operation.
