Working Principle

637L14835I3T is an integrated-circuit based crystal oscillator. Inside the oscillator, two crystal resonators will provide a reference frequency input when driven by an external DC voltage. Generally, the higher the Q factor of the crystal resonation the better the frequency stability and the higher the frequency stability the better the performance.

An amplifier is integrated inside the oscillator and the gain is adjusted by resistors. When an AC signal is input, the amplifier will amplify the input signal to match the crystal resonator requirements (about 0.8 – 1.25V) and drive the crystal resonator. When the frequency of the amplified signal matches the crystal resonator, the oscillator will output a continuous wave with frequency determined by the crystal resonation.
