Working Principle of ECS-51-20-1X

ECS-51-20-1X works through the use of the mechanical resonance effect. When a voltage is applied to the crystal, it vibrates at its fundamental resonance frequency. This vibration causes the surrounding air molecules to vibrate at this frequency as well, creating an electromagnetic field around the crystal. When the circuit is connected to the crystal, it captures the vibration and uses it to determine the clock speed of the system. Therefore, by controlling the voltage applied to the crystal, the clock speed can be accurately determined and controlled.
