Working Principle

The 633L12506A3T oscillator uses a quartz crystal to generate stable frequency. The quartz crystal is a piezoelectric device that vibrates at a specific frequency when a specific voltage is applied. The frequency of the vibration is affected by the size, shape, and temperature of the crystal, and the circuit components around it.

The actual operation of the oscillator is achieved by the tank circuit, which is composed of two parallel quartz crystals and a capacitor. The quartz crystals act as a frequency-determining element and the capacitor modulates the frequency. The oscillator works by creating a voltage feedback loop between the quartz crystal and the capacitor. As the capacitor discharges, a voltage is created across the quartz crystal, causing it to vibrate. This, in turn, induces a current and the capacitor starts to charge up again. The process is repeated and the frequency is determined by the values of the quartz crystal and the capacitor.

The device also includes other components such as an amplifier and a timing resistor, which are necessary for its operation. The amplifier amplifies the signal from the quartz crystal, while the timing resistor is used to fine-tune the frequency output by the oscillator. The amplifier also ensures that the output signal is strong enough to be used in various applications.
