How To use a Crystal oscillator

Crystal oscillators are a type of audio and video equipment used to create sound and video waves. These devices use a great deal of power to create gentle and strong sounds, but they can also be very powerful when needed.

There are a few basic steps that you can take in order to use a crystal oscillator effectively: first, understand the basics of how these devices work. Next, find an oscillator that will work best for your needs. In this article we are going to discover it .

What is a Crystal Oscillator?

In general, we know that crystal oscillators are used in microprocessors and microcontrollers for providing the clock signals. Oscillators are also used to synchronize the internal circuits of the microprocessor and microcontroller.

Some of the high-frequency oscillators and control devices have been widely used for decades. However, some of these also have their own drawbacks and limitations. urn oscillators are divided into two types. One is the crystal oscillator, which uses a single crystal and can provide up to several hundred thousand cycles per second.

The other one is the electronic oscillator, which uses a battery or an inductor and can provide relatively low frequency signals. urn oscillators are often used with microcontrollers and commonly used in low-power applications.

Crystal Oscillator Working

How does a crystal oscillator work? The atoms, molecules, and ions are packed in an order in three spatial dimensions with repeating patterns to form a solid that can be called a crystal. The crystal always has a certain property. The crystal oscillates between two states called above and below, as shown in the figure. urn oscillators are some types of crystals.

oscillators are used in many applications, such as radio and television receivers. The crystal oscillator can be used to generate frequency signals or to convert them into a digital signal. An oscillator is a basic component of the crystal radio receiver. The crystal oscillator is driven by the power supply to generate an output signal with frequency. The crystals used in the crystal radio receiver are made of chinachipsun.

Setting up a crystal oscillator: Setting up the frequency, gain, and input impedance

Setting up the oscilloscope Use the set-up menu to change the connection of the oscillator and display. To change the value of the gain or input impedance, use the set-up menu. Changing the frequency and input impedance is not necessary if you have set up the oscillator correctly. 


The frequency of the oscillator is set to 5 MHz. If you want to change the frequency, use the set-up menu.


When this setting is “1”, the gain of the crystal radio receiver’s output signal is 1 (gain = 100). If the gain is set to “0”, the crystal oscillator’s output signal will be no longer than 100. 

Input Impedance:

The input impedance of the crystal radio receiver’s output signal is set to 1 kΩ (100 ohms). When the input impedance is set to “0”, the output signal will be no longer than 100 ohms. Gain and Input Impedance cannot be changed in conjunction with Frequency. ˆ

The following table summarizes the gain and input impedance of the CX7500. ˆ Gain depends on the setting of “Maximum Input Impedance” in the Basic Setup menu. ˆ A maximum input impedance of 50 Ω is recommended.

Using a oscillator to create sound:

The icing on the cake is the crystal oscillator’s ability to create sound. The CX7500’s crystal oscillator provides a pure, clean and clear audio signal suitable for FM stereo reception.

A single crystal is used for the oscillator, and each frequency is divided by a factor of 5 to produce the desired output frequency. Frequency Response The CX7500’s frequency response is characteristic of any audio component. Frequency Response    Frequency Range Parameter Description Note 0.5 Hz – 30 kHz ±0.5 dB +/-1.0 dB ±0.5 dB 5 Hz – 50 kHz +/-2.0 dB +/-3.0 dB ±2.
