Product Introduction

   The LX-A40 CPT atomic clock is a miniature atomic clock based on the principle of coherent population trapping, which outputs an accurate and stable 10MHz standard frequency signal and 1PPS pulse signal. The installation size of the LX-A40 CPT atomic clock is compatible with the SA.45s chip clock, and it can work in time and frequency boards and modules, and has a UART frequency calibration interface and an external electric adjustment interface.
