TCA55 Localization Chip level Atomic clock

Learn about our Localization Chip level Atomic clock

The CA55 is a domestically produced chip-level atomic clock based on the CPT principle, offering advantages such as low power consumption, compact size, and fast startup. Suitable for operating temperatures from -40°C to +85°C, it provides CMOS-level 10MHz and 1PPS outputs, boasting short-term stability better than 3E-10/1s, daily drift better than 3E-11, and monthly aging less than 5E-10. It supports external calibration using 1PPS or analog voltage, making it suitable for applications such as navigation, communications, unmanned equipment, marine geophysical exploration, and instrumentation.
