What will happen if the crystal oscillator is broken?

The common phenomenon of crystal oscillator damage is: the clock signal is unstable or lost. The device cannot start. Abnormal frequency. Increased noise. Abnormal power consumption.

Common phenomena of crystal oscillator damage

Crystal oscillator, that is, crystal resonator, is a common component in electronic circuits. Its main function is to provide stable and precise clock signals. When the crystal oscillator is damaged, the following phenomena will occur:

1. The clock signal is unstable or lost

The crystal oscillator is the core component of the clock circuit, and its damage will As a result, the clock signal is unstable or lost directly. The symptoms are that the equipment cannot work properly, such as the computer cannot enter the system when it is turned on, the time display on the electronic watch is incorrect, etc.

2. The device cannot be started

In some circuits, the crystal oscillator is a necessary component for the device to start. When the crystal oscillator is damaged, the device may not start from the shutdown state.

3. Frequency Abnormality

Damage to the crystal oscillator will cause its output frequency to be abnormal, which may manifest as a clock frequency that is too fast or too slow. This can cause the device to operate abnormally and cause various problems.

4. Increased noise

When the crystal oscillator is damaged, noise may appear in its output signal, which manifests itself as abnormal sound from the device, such as a sharp sound from a computer. , the ticking sound from the electronic watch becomes irregular, etc.

5. Abnormal power consumption

A damaged crystal oscillator may cause an increase or decrease in circuit power consumption, which manifests as increased device heat or shortened battery life.
