Clock chip RTC principle introduction, crystal oscillator selection, application scenarios

Clock chips are widely used in communication equipment, consumer electronics, industrial control, automotive electronics, Internet of Things and smart home.

The difference between VCXO crystal oscillator and TCXO crystal oscillator

In many applications, we can use the DAC function of the microcontroller to control the bias voltage of the VCXO and adjust the output frequency of the VCXO.

What does the crystal oscillator rely on to start oscillation?

Simply put, the driving force behind the oscillation of a crystal oscillator is electricity. We need to place a crystal oscillator in a complete circuit and power the circuit to generate a loop current. From then on, the crystal oscillator begins to "beat" steadily and rhythmically.

Get rid of the anxiety of "not being able to find"! UWB allows positioning to be accurate to the centimeter level!

Behind the smooth and accurate experience provided by AirTag and digital car keys, a key high-precision positioning and spatial perception technology is playing a key role - UWB (Ultra-wide Band)
