FAQ
What are crystals, oscillators, and resonators used for?
Crystals, oscillators, and resonators are electronic components used in various electronic circuits to provide timing, frequency control, and signal stability. Crystals are passive components that generate a precise frequency when voltage is applied and are commonly used in clock circuits for microcontrollers, processors, and communication devices. Oscillators are active components that produce an oscillating signal at a specific frequency and are utilized in applications such as signal generation, clock synchronization, and frequency modulation. Resonators are passive components that resonate at a specific frequency and are often used as timing references in circuits where stability and accuracy are essential, such as in radio frequency (RF) communication systems and audio equipment. Overall, crystals, oscillators, and resonators play critical roles in controlling frequencies, maintaining accurate timing, and ensuring signal integrity in electronic devices.
How do crystals, oscillators, and resonators work?
Crystals, oscillators, and resonators function based on the principle of resonance and feedback mechanisms to generate and control specific frequencies in electronic circuits.Crystals are natural or synthetic materials that exhibit piezoelectric properties. When an electric field is applied, they vibrate at a specific frequency determined by their physical characteristics. In electronic circuits, crystals are cut and shaped to resonate at precise frequencies, providing a stable time base for timing applications.Oscillators are electronic circuits that generate periodic waveforms at a particular frequency. They typically consist of an amplifier and a feedback network. The feedback loop sustains oscillations by feeding a portion of the output signal back to the input with the proper phase and magnitude to maintain the desired frequency. Oscillators can be designed using various configurations such as LC, RC, and crystal oscillators.Resonators are passive electronic components that exhibit resonance at specific frequencies. They can be made of various materials like ceramic, quartz, or surface acoustic wave (SAW) materials. Resonators are used to stabilize and control frequencies in circuits by providing a precise response at their resonant frequency. They are often employed in filters, sensors, and tuning circuits where frequency accuracy and stability are crucial.
How are crystal oscillator made？
Crystal oscillator manufacturing process is a common electronic component manufacturing technology, mainly used in electronic equipment clock circuit, frequency control circuit and so on. Its production step consists of 5 steps, the first need to prepare the crystal sheet, usually quartz crystal sheet. The second is electrode production, both sides of the crystal sheet need to make electrodes, usually using metal electrodes, such as aluminum electrodes, silver electrodes and so on. The third step is sheet welding, where the electrodes on both sides are connected to the crystal sheet to form the basic structure of the crystal oscillator. The fourth step needs to be tested after the production is completed, and the test items include resonant frequency, resonant impedance, frequency stability and other parameters. The final step is encapsulation.
What is the frequency of crystal oscillation?
The range of crystal oscillation frequency depends on the structure and manufacturing process of the crystal resonator. Depending on the application, the crystal oscillation frequency can range from several thousand Hertz to several hundred megahertz. For example, for some systems that require high-precision clock signals and stable oscillation frequencies, the commonly used crystal frequencies are 4MHz, 8MHz, 12MHz, 16MHz, and so on. For wireless devices that need high-speed communication, the commonly used crystal frequency is 40MHz, 50MHz, 60MHz, etc. These frequency ranges are determined based on the physical properties of the crystal, such as elasticity and thermal stability.If you want to control the frequency of a crystal oscillator, you can adjust it by selecting a crystal with the desired fundamental frequency or by using frequency control components like capacitors in the oscillator circuit. Capacitors are often used to fine-tune the frequency of the crystal oscillator.
How much of Crystals oscillators resonators?
The price of crystal oscillators and resonators depends on a number of factors, including brand, model, frequency, accuracy and quality. In general, crystal oscillators are usually more expensive than resonators because crystal oscillators provide more stable and precise frequencies. Crystal oscillators can cost anywhere from a few dollars to tens of dollars, depending on their specifications and performance. The price of resonators is affected by similar factors, but is usually relatively cheaper. When buying a crystal oscillator or resonator, it is recommended to choose the right model and brand according to the specific needs, and refer to the quotation of different suppliers to obtain the most competitive price. In Jak electronics, you will find the latest supplier quotes.
What is the difference between crystal oscillator and crystal resonator?
Crystal resonators and crystal oscillators have obvious differences in working principle and use. In principle, a crystal resonator is an electronic component that utilizes the piezoelectric effect of a quartz crystal (also known as a crystal). When a quartz crystal is subjected to an external force, it generates an electric charge that is proportional to the frequency of the external force. Therefore, by adjusting the frequency of the external circuit, the quartz crystal can be made to produce a signal of a specific frequency. Crystal resonators are commonly used to generate high-precision frequency reference signals for use in clock circuits of various electronic devices. A crystal oscillator is a type of oscillator that uses a quartz crystal as a resonator. It makes the crystal oscillate freely by adding an appropriate excitation signal to the quartz crystal. The frequency stability of the output signal of the crystal oscillator depends on the frequency stability of the quartz crystal and the amplitude of the excitation signal. Crystal oscillators are commonly used to generate high frequency signals, such as microwave signals or radio frequency signals, for use in various communication systems. In terms of use, crystal resonators are mainly used for the generation of high-precision frequency reference signals, and crystal oscillators are mainly used for the generation of high-frequency signals.
