High performance rubidium atomic clock

Product Introduction

   The LX-A45 chip atomic clock is a miniature atomic clock based on the coherent population trapping principle and MEMS technology. It outputs an accurate and stable 10MHz standard frequency signal and 1PPS pulse signal. The installation size of the LX-A45 chip atomic clock is compatible with the SA.45s chip clock, and it can work in time and frequency boards and modules. It has a UART frequency calibration interface and an external electrical adjustment interface.
