Crystals: CFV-20660000DZFB

Crystals are small tunable vibrating objects made of sparkling rock or quartz, and CFV-20660000DZFB crystals are the world\'s leading frequency-tunable type. Its primary use is in applications where frequency-tunable signals are required, such as communications systems or frequency synthesizers. For example, in frequency hopping radios, a CFV-20660000DZFB crystal will replace the phase-locked loop for better performance and lower costs.

Application Field:

CFV-20660000DZFB crystals are used in various communication systems such as cellular telecommunication systems, digital terrestrial television broadcasting systems, digital audio broadcasting systems, and radio navigation systems. They are also used in various frequency synthesizers in research and medical devices such as spectrophotometers. In computer applications, they are used in onboard devices to generate clock signals.

In addition, CFV-20660000DZFB crystals are often employed in avionics, aircraft engines, and naval propulsion systems, where precision is a key objective. They are used to measure and control time and frequency for a wide range of military operations. They are used in tracking missile direction, boresighting and range finding, ballistic studies, and clock reference for air launches and radar or ECM systems.

Working Principle:

CFV-20660000DZFB crystal is composed of microelectromechanical system (MEMS) technology and advanced microfabricated packaging techniques. Its main working principle is to use an internal piezoelectric transducer to convert the AC voltage of different frequencies into mechanical displacement of the crystal reed. The two electrodes of the crystal reed are connected to two sets of capacitors and resistors which form the series resonance circuit.

During operation, the frequency generated by the piezoelectric transducer is altered by the capacitance of the series resonance circuit. These changes of capacitance modify the oscillator frequency, making the crystal reed vibrate at different frequencies as desired. Tuning the frequency is done by changing the piezoelectric transducer\'s input voltage. This process is known as dynamic voltage tuning.

The CFV-20660000DZFB has a wide frequency range, from 4kHz to 10GHz, with a bandwidth of 2MHz and a tuning range up to 2GHz. The frequency accuracy is typically 2.5 ppm, making it ideal for applications where precise and reliable tuning is required.

In short, CFV-20660000DZFB crystals are extremely versatile and can be employed in a wide variety of applications ranging from communications to military operations. Their wide tuning range and excellent frequency accuracy make them one of the best products on the market.
