Crystals: 9B-7.680MBBK-B Application Field and Working Principle

Crystals have become instrumental components in modern technology and their application range significantly wide. As an example of such component, the 9B-7.68MBBBK-B crystal can be used for various applications, mainly frequency control and oscillation, for both voltage controlled (VCXO) and temperature controlled (TCXO).First and foremost, the 9B-7.68MBBBK-B crystal is best suitable for frequency control applications, such as frequency synthesizers, voltage controlled oscillators and other frequency modulation circuits. The device is designed to generate accurate frequency to the order of tens to hundreds MHz, far higher than most crystal frequencies that can be obtained from simple crystal oscillators. As such, the 9B-7.68MBBBK-B crystal is mainly used as building block component in modern radio frequency (RF) communication systems, such as global positioning system (GPS), cellular, satellite, and Wi-Fi.Furthermore, the temperature compensated crystal oscillator (TCXO) design yields tight frequency and temperature coefficient (TC) control, in addition to higher frequency stability. This is made possible by incorporating a temperature sensing device within the circuit, which allows for the greatest precision in frequency generation. This device is suitable for various wireless communication applications, in which temperature fluctuation is a major source of signal impairment.In conclusion, the 9B-7.68MBBBK-B crystal is a high-accuracy, low-cost frequency and temperature controller oscillator that is suitable for a variety of frequency control applications, such as voltage controlled oscillators and temperature compensated crystal oscillators. It offers higher frequency stability, higher frequency accuracy, and tighter temperature coefficient (TC) control, allowing it to be used in modern radio frequency communication applications, such as GPS, cellular, satellite, and Wi-Fi.
