Crystals

Crystals are an essential and increasingly important part of modern life. They have an enormous array of applications, from medical imaging to clock designs and from radio frequency (RF) systems to cellphone transceivers. Of particular relevance to this article is the AV-24.305MAHY-T crystal oscillator which can be used as a frequency standard in any number of electronic systems. This article will discuss the application field of the AV-24.305MAHY-T crystal oscillator and its working principle.

What is a Crystal Oscillator?

A crystal oscillator is a type of electrical oscillator that uses a quartz crystal as its oscillating element. These devices provide a precision frequency reference for radio frequency (RF) systems, digital electronics, and communication systems. The quartz crystal undergoes mechanical stress when an electric field is applied to it; thus, creating a tunable filter with a very sharp frequency response. Quartz crystals come in a variety of shapes and sizes, with the most common being the AT cut, which is what the AV-24.305MAHY-T uses.

Application Field of AV-24.305MAHY-T

The AV-24.305MAHY-T crystal oscillator is part of the MAHY family of Crystal Oscillators from Abracon Corporation. This oscillator is used in a number of applications, including frequency stabilization in clocks, watches and biomedical instruments, data processing, frequency synthesis, and waveform generation. It is a tiny, yet powerful oscillator, capable of providing a frequency up to 24.305MHz with a temperature stability of 0.5ppm/°C.

The AV-24.305MAHY-T is also ideal for use in consumer electronics such as television sets, Hi-Fi systems, car audio systems, and portable devices, thanks to its low profile and small size (4.0 x 2.4mm). Its industry-standard 3-Pin package and wide operating temperature range of -40 to 85°C make it an ideal choice for a variety of consumer electronics.

Working Principle of AV-24.305MAHY-T

The AV-24.305MAHY-T crystal oscillator works by applying an alternating voltage to the quartz crystal, causing it to vibrate and generate an electrical signal. This signal is then amplified and sent to an output terminal. The frequency of the oscillation is determined by the size and shape of the crystal and can range from a few kilohertz (kHz) up to hundreds of megahertz (MHz). The advantage of using quartz crystals over other oscillator types is that they provide a much more precise frequency, as they are not affected by environmental factors like temperature or pressure.

The AV-24.305MAHY-T is an AT-cut quartz crystal, which is made up of two plates that are cut at an angle of 9°. The plate is then mounted to a base plate and an electrical field is applied to the crystal, causing it to oscillate. The angle of the cut determines the frequency of the oscillator – the higher the angle, the higher the frequency. As the crystal vibrates, its resonance is detected by the oscillator’s feedback circuit, which then adjusts the electrical current to ensure that the proper frequency is maintained.

Conclusion

The AV-24.305MAHY-T crystal oscillator is an essential component in many modern electronic devices. It provides a precise frequency reference and stability to radios, medical instruments, clocks, and a variety of consumer electronics. Its low size and wide operating temperature range make it an ideal choice for these applications. This article provided an overview of the application field and the working principle of the AV-24.305MAHY-T crystal oscillator.
