OscillatorsA crystal oscillator is a circuit that achieves a very precise frequency, or multipe frequencies, by amplifying the vibrational energy of a quartz crystal. ASTMUPCFL-33-32.000MHZ-EY-E-T is such an oscillator working at 32.000MHz frequency, and is widely used in many applications.Application FieldASTMUPCFL-33-32.000MHZ-EY-E-T oscillators are especially designed for integration into large scale integrated circuits (LSI) to control their internal operating frequencies. These oscillators have become one of the most widely used forms of oscillators on the market, as they provide a reliable way for producing frequencies of high precision. They are used in consumer electronics, as well as in professional instruments and audio devices. This type of oscillator is also commonly used in communications applications, including mobile phones, satellites, and computer and internet networks. In addition, they are employed to monitor and control systems such as air traffic control, security systems, vehicle safety systems, and robotics. In medical applications too, they can be used for radiometry and precise timing.Working PrincipleThe ASTMUPCFL-33-32.000MHZ-EY-E-T oscillator is an electrostatically-driven quartz crystal oscillator. The oscillator contains a quartz crystal housed in a holder manufactured from macroscopically anisotropic materials. When electricity passes through the holder, it creates a force known as ‘pull-in force’. This force causes the crystal to vibrate, resulting in electricity peaks and troughs at the output of the oscillator. The frequency of this output is determined by the ‘resonant frequency’ of the quartz crystal.To produce the optimal performance and stability from an oscillator, the crystal is typically aligned to its optimum ‘cap’ position, that is the point of greatest resonance. The holder’s macroscopic anisotropy helps stabilise the crystal in relation to the oscillator’s electrical field. The capacitors and the circuit design are optimised to best use this resonance.By monitoring small frequency drifts due to changes in temperature, the output frequency and stability is maintained over a range of operating temperatures. This ensures that the device’s frequency remains precise and that its performance is consistent in varying climates.The ASTMUPCFL-33-32.000MHZ-EY-E-T oscillator is suitable for all applications that require highly precise oscillation of frequencies around the 32.000MHz range. Its ability to provide a high degree of precision across an extensive temperature range of operation makes it a highly sought-after solution in many industries.
