CPPC7-B6-40.0TS Application Field and Working Principle

Crystal oscillators are electromechanical devices which can protect a certain electric frequency in a certain range. CPPC7-B6-40.0TS crystal oscillators belong to ceramic package crystal oscillators. They have small volume, simple structure, low frequency measurement accuracy, and stable performance. The working principle of this type of oscillator is based on the Faraday-Law of Combined Electromagnetic Induction, showing a similar electric oscillation process of the LC oscillator.

The application field of CPPC7-B6-40.0TS crystal oscillators covers a wide range. For example, in the communication industry, it can be used for the local oscillator in frequency conversion, the local oscillator of signal transmission equipment and the oscillation circuit of test and measurement instruments; in the industrial automation industry, it can be used for the oscillation circuit of digital devices, electronic control process control; in the consumer electronics industry, it can be used for the application of wireless LAN, television, computer display, etc. In addition, it can also be used for general electronic applications such as clock signal generators, alarm clocks, test instruments and game consoles.

The basic working principle of CPPC7-B6-40.0TS crystal oscillator consists of two basic components, a quartz crystal and electronic circuits. A quartz crystal is a piezoelectric substance that allows displacement voltage to pass through when the applied force changes. The electronic circuits are composed of inductor, resistor and capacitor (LRC resonance circuit). A quartz crystal composed of a pair of metal plates is mounted in the center connecting the two sides of the LRC resonance circuit, and the circuit is sealed in a ceramic block.

When a square wave signal is applied to the pad of the oscillator, the quartz crystal will have a displacement voltage that is several orders of magnitude higher than the signal applied to the oscillator. Through the coupling between the two electrodes of the crystal, the displacement voltage of the crystal is transmitted to the loop to form an oscillation signal, and the circuit will work stably at a certain frequency. The loop continuously feeds back the signal to the crystal to continue the oscillation process until the oscillator\'s output is slightly larger than the oscillator\'s power supply, thus achieving the function of oscillation.

In conclusion, CPPC7-B6-40.0TS crystal oscillators have wide application areas, and their working principle is based on the Faraday-Law of Combined Electromagnetic Induction. It uses the combination of quartz crystal and electronic circuits to achieve stable oscillation, thereby achieving the purpose of generating a stable frequency signal.
