402F26011CJT Application Field and Working Principle

Crystals form the foundation of many different types of electronic equipment. They are used in a variety of forms including oscillators, phase-locked loops (PLLs), and frequency synthesizers. The 402F26011CJT crystal is among the more versatile crystals available. Let\'s take a look at its application field and working principle.The 402F26011CJT crystal is most commonly used in PLLs and frequency synthesizers. A PLL uses a VCO (voltage-controlled oscillator) to begin its operation. The VCO generates a frequency, and the signal from it is used to lock the 402F26011CJT oscillator. This is done by it receiving the appropriate control voltage according to the particular frequency that is transmitted.The frequency of the crystal can be determined from the voltage applied to it. For example, a voltage of 1V will generate a frequency of 2 MHz, and a voltage of 1.5V will generate a frequency of 3 MHz. The amount of the variation is known as the tuning range. The 402F26011CJT crystal has a tuning range of 0.5 to 1V, and it has a maximum rated frequency of 30MHz.The 402F26011CJT crystal is a quad-element, resonator-type oscillator. It consists of four piezoelectric electromechanical resonators that are connected in an alternating pattern. The alternating pattern enables the crystal to receive an alternating voltage and generate an alternating current. The alternating current is then used to drive the crystal at the desired frequency. This frequency is determined by the resonance of the crystal\'s lattice structure.The frequency of the 402F26011CJT crystal is generated by changing the voltage of a bias potentiometer. The bias potentiometer is connected to the grounding line of the crystal. As the voltage of the potentiometer is adjusted, the bias voltage of the crystal is also adjusted. This changes the frequency of the crystal, and the frequency is then sent to the oscillator circuit.The bias voltage of the crystal is used to control the amplitude of the oscillations. When the bias voltage is increased, the amplitude of the oscillations increases. This increases the frequency of the oscillator. The frequency can then be adjusted by using the bias potentiometer. The frequency of the oscillator will remain at the same level for as long as the bias voltage remains the same.The 402F26011CJT crystal is a very reliable device and is widely used in PLLs and frequency synthesizers. Its wide tuning range makes it ideal for use in applications where precise frequency control is needed. Its ability to remain stable for long periods of time without requiring additional tuning makes it a preferred choice for those needing frequency-stable oscillators. The 402F26011CJT crystal is perfect for those needing a reliable and accurate source of electronic signals.
