Working Principle

The SIT9120AC-2B1-25E50.000000D oscillator is an electronic oscillator based on CMOS technology. It uses a voltage controlled oscillator (VCO) to generate a stable clock signal of a specific frequency. The internal phase-lock loop (PLL) and crystal oscillator are used to provide better frequency accuracy and stability.

The VCO consists of a circuit based on an operational amplifier. The frequency of the output signal is controlled by the voltage of the input voltage. When the voltage changes, the feedback loop of the operational amplifier increases or decreases the gain. This changes the frequency of the output signal.

The PLL is a circuit that helps to generate better frequency accuracy and stability. The PLL consists of a voltage controlled oscillator and a frequency divider. The divider is used to divide the output signal from the VCO. This divides the frequency of the output signal which is then compared with a reference signal. The difference is used to adjust the voltage of the VCO thus controlling the frequency of the output signal.

The crystal oscillator is used as a reference frequency to ensure accuracy and stability. The crystal oscillator has an oscillation frequency which is lower than the desired frequency. The output signal from the crystal oscillator is divided and compared with the output of the VCO. The difference between the two signals is used to adjust the VCO thus providing precise frequency control.

The SIT9120AC-2B1-25E50.000000D oscillator is a reliable and accurate electronic oscillator suitable for various electronic applications including radios, medical equipment, consumer electronics, automotive industry, computer and peripherals, and other high-tech fields due to its frequency range, supply voltage, stability, accuracy, low power consumption, and small size.
