Wireless module's crystal oscillator's function

When you buy a wireless module, you will find that whether the wireless module has a crystal oscillator is specifically marked in the parameter column. Question: What is a crystal oscillator? What's the function of crystal oscillator in wireless module? Will the crystal oscillator affect the wireless module?

What is the crystal oscillator in the wireless module?

The crystal oscillator in the wireless module is the abbreviation of the quartz oscillator, and it is an important part of the clock circuit.

What's the function of crystal oscillator in wireless module?

The main function of the crystal oscillator is to provide a reference frequency for the chips and various components in the wireless module. Usually a system shares a crystal oscillator to facilitate the synchronization of all parts. Some communication equipment systems use different crystal oscillators for the fundamental frequency and radio frequency, and they are synchronized by electronically adjusting the frequency.

Will the crystal oscillator affect the wireless module?

Everyone knows that the wireless module uses the microcontroller to achieve communication, and the crystal oscillator plays a very important role in the microcontroller system. It is the clock in the microcontroller system and has a fixed and stable frequency. In the digital circuit world, it is based on The beat is used for processing, and the crystal oscillator provides this fixed and stable beat, so that the wireless module and the program of the single-chip computer can run normally. Without this crystal, it may cause the program to be disordered or stagnant. In summary, the crystal oscillator provides a clock circuit for the wireless module. Just like our time system in real time, if our time is stagnant, we will freeze or freeze in the time period when time is stagnant. The crystal oscillator also gives the wireless module time to allow it to operate normally.
