Working Principle

The SIT9120AI-2C3-25E133.000000X Oscillator is designed to work on the principle of a resistor-capacitor (RC) oscillator using a ceramic resonator as a frequency-determining element. The oscillator comprises an RC resonator, an inverter buffer, and a temperature compensating capacitor. Trim capacitors on the input side of the inverter buffer allow for frequency adjustment and provide excellent circuit flexibility. When an oscillator is powered up, the oscillator begins to oscillate and produce an output signal at its specified frequency. The frequency of rotation is determined by the time constant of the RC circuit.

In addition, a voltage regulator ensures steady voltage output levels at different supply voltage and temperature levels. This voltage regulator is supported by a low-dropout regulator, which is designed to help maintain a stable frequency and low current consumption. The voltage regulator also enables the oscillator to operate in extreme temperatures (-40 to +125C) and environments.

The SIT9120AI-2C3-25E133.000000X Oscillator is ideal for radio communication, telecommunications, consumer electronics, and automotive applications, where low power consumption, low operating voltage, and high frequency stability are required. The oscillator has an adjustable operating range of 0.0045-33.00MHz, making it a perfect choice for applications that require highly stable and precise frequency control.
