What are the connection methods for crystal oscillators?

In practical applications, the choice between an internal or external crystal oscillator mainly depends on specific application requirements and circuit design. For example, in some applications that require strict space requirements or high integration, internal crystal oscillators may be more preferred.

What is the difference between crystal oscillators and crystals

When it comes to crystal oscillators, one may think of quartz crystals. In fact, these two are equivalent. So what is the difference between crystal oscillators and crystals? Give a brief analysis.

Does the thickness of the chip affect the frequency of the crystal oscillator?

The thickness of the chip is one of the key factors determining the frequency parameters of the crystal oscillator. The thinner the chip, the higher its oscillation frequency. This is because the thickness of the chip determines the characteristics of its vibration mode. Under the same excitation conditions, thinner chips are more likely to generate high-frequency vibrations. For example, a 40MHz crystal oscillator typically requires a chip thickness of around 41.75 microns to achieve
