Application circuit of CSJ-R05B and single chip microcomputer

CSJ-R05B is an industrial-grade superheterodyne micro-receiver component. It is expanded by adding a local oscillator stabilized by a surface acoustic wave resonator and a sleep (power saving) control circuit based on the CSJ-R05A component. It has good adaptability to changes in temperature, power supply voltage and use environment, and can meet the use requirements in relatively harsh environments. The application circuit of CSJ-R05B and a single-chip microcomputer is shown in the figure below.
