Working Principle

The 637P14835I2T oscillator is based on a classic architecture using an X-tal resonator oscillator circuit with an output buffer stage. It consists of a tuned LC resonant circuit and two complementary transistors that work together to produce a square wave output. The main portion of the oscillator, the tuned LC, is composed of a capacitor and inductor connected in series. The circuit is inversely proportional to the external environment voltage supplied and it oscillates with the driving of an external crystal. The output stage is used to buffer the output signal from the LC resonator portion of the circuit by stabilizing amplitude, shape, and frequency of the signal.

The frequency of the 637P14835I2T oscillator is dependent on the resonant frequency of the LC circuit. As the population value of the external environment voltage increases, the instantaneous frequency of the oscillator will also increase. Therefore, the 637P14835I2T oscillator is designed to operate over a wide voltage and temperature range. Additionally, since the resonance of the LC circuit is relatively narrow, it is also hard to be affected by outside capacitors or inductors which makes it a very reliable oscillator.
