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.

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

石英晶體與頻率控制組件
石英是由硅原子和氧原子組合而成的二氧化硅（Silicon Dioxide, SiO2）, 以32點(diǎn)群的六方晶系形成的單結(jié)晶結(jié)構(gòu)﹝圖一﹞.單結(jié)晶的石英晶體結(jié)構(gòu)具有壓電效應(yīng)特性, 當(dāng)施加壓力在晶體某些方向時(shí), 垂直施力的方向就會(huì)產(chǎn)生電氣電位. 相對(duì)的當(dāng)以一個(gè)電場(chǎng)施加在石英晶體某些軸向時(shí), 在另一些方向就會(huì)產(chǎn)生變形或振動(dòng)現(xiàn)象. 掌握單結(jié)晶石英材料的這種壓電效應(yīng), 利用其發(fā)生共振頻率的特性, 發(fā)揮其精確程度作為各類型頻率信號(hào)的參考基準(zhǔn)
