The present invention relates to a CPT atomic clock servo control SoC, which includes a microprocessor, a photoelectric signal demodulation functional module, a temperature control loop functional module, a laser and microwave loop control functional module, a C field control functional module, and a bus bridge. The bus bridge is connected to a system bus and a peripheral bus, for connecting to buses with different speeds. The photoelectric signal demodulation functional module extracts power change information of a microwave and a laser. The temperature control loop functional module controls temperatures of an absorption cell and a laser tube. The laser and microwave loop control functional module implements laser frequency locking and microwave loop locking. The C field control functional module provides a stable C field for the absorption cell.
