It is often used as a timing or frequency reference to control the clock frequency in signal processing systems. It is also used in digital circuits to generate clock signals for various operations. Additionally, it is used in precision motors, water pumps, and air-conditioners to maintain the accuracy of the motor movement.

Working Principle

The 637L10622I3T oscillator works by using the PLL technique to lock its output frequency to the input reference frequency. The PLL circuit consists of a voltage-controlled oscillator (VCO), a phase detector, and a digital divider. The input reference frequency is compared to the VCO output by the phase detector. The digital divider is used to generate an output frequency whose period is an exact multiple of the input reference frequency. This feedback system causes the output frequency to be locked to the input reference frequency.

To control the frequency of the output signal, a capacitive voltage divider is used. When a positive voltage is applied, the capacitance increases, thereby causing the frequency to decrease. Conversely, when a negative voltage is applied, the frequency increases. This allows for control of the output frequency with varying input voltage levels.
