The specified operating range is 1.132800 MHz to 1.163800 MHz, so it is used in applications which require highly precise frequency.

The working principle of SIT9120AC-1C3-33E161.132800Y is based on the Pierce oscillator. The circuit consists of an active device, usually a bipolar transistor, a resistor and a parallel tuneable capacitor, typically varactor diode. The varactor diode is tuned with the help of a control signal applied directly to the varactor diode to control the resonant frequency.

The oscillator is connected to a power source. The active device in the oscillator acts as an amplifier and when given a biasing current, the transistor will amplify a weak signal at the tuned frequency. The capacitor and the resistor will act as a tuned resonator, resonating at a specific frequency, and the active device will amplify this signal. The amplified signal will be fed to the active device which will then amplify the signal again, this process will be repeated over and over, creating an oscillating signal for a desired frequency.

The oscillator can either be used in a free running state or locked to an external reference oscillator. The external reference oscillator can be used to stabilize the oscillating frequency, allowing the output frequency to remain very accurate and stable. This is especially useful in applications where high accuracy and precise frequency is essential.

In summary, the SIT9120AC-1C3-33E161.132800Y is a miniature size oscillator which can produce a stable and accurate oscillation across a wide frequency range. It is used to generate precise frequencies in a variety of industries and applications, from communications systems to data acquisition.
