Product profile
The TCA55 is a new type of atomic clock based on the principle of Coherent Population Trapping (CPT), with the advantages of low power consumption, small size and fast startup, etc. The TCA55 is developed and produced by domestic components and process technology, and can guarantee the frequency accuracy of ppb level in the operating range of -40 ℃ ~+85 ℃ . The TCA55 outputs CMOS level 10MHz square wave and 1PPS pulses with short-term stability better than 3E-10/1s, daily drift better than 3E-11, and monthly aging rate better than 5E-10. The TCA55 has an external calibration function, which can be done by external 1PPS signals or external analog voltages. The TCA55 has better reliability and flexibility, such as controlling its output frequency and querying its internal health status. The frequency can be adjusted via the RS-232 serial port or calibrated using an external 1pps signal with a calibration resolution of <1E-12.
