Oscillators

Oscillators are electrical circuits or components which produce a repetitive and periodic output signal. Depending on the frequency of the output signal, they are divided into low-frequency oscillators (LFOs) and high-frequency oscillators (HFOs). LFOs are used in precision control and timing applications like digital circuitry, audio, radio, and automotive systems, while HFOs are used in high capacity communication systems like wireless networks and satellite systems.

633P13305I2T is a type of oscillator used to generate a periodic signal for a specific frequency. It is a small, hermetically sealed, crystal oscillator with a ceramic package and incorporates an oscillator circuit, a frequency control voltage, a temperature compensated resonator, and an oscillation frequency capacitor. The main application of this device is providing a reliable and stable timing and control reference source.

Working Principle

633P13305I2T oscillator works according to the concept of the LC oscillator, in which current flows through the series capacitor-inductor combination in a circle. The capacitor is charged and discharged through the inductor, which creates oscillations with a specific frequency. The device is powered by a DC voltage, which enters the oscillating tank circuit and sets up a continuous AC current for oscillation.

The oscillator consists of several components integrated on one integrated circuit including the crystal resonator, oscillator circuit, passives, and ESD protection structures. The crystal resonator of the circuit is connected to the oscillation frequency capacitor and the oscillator circuit generates an oscillating electrical signal by connecting the resonator to the capacitor. The oscillation frequency capacitor is used to control the frequency of the oscillations.

When the oscillator is powered, the oscillation frequency capacitor will begin to store electric charge to generate the repetitive and periodic output signal of a certain frequency. The oscillator will then generate a square wave output signal, with frequency adjustable by a voltage applied externally to the device. This signal can then be used as a reference signal for digital circuitry, audio, radio, automotive systems, wireless networks, and satellite systems.
