Crystals

Crystals are a vital component utilized in many electronic circuits. For example, crystals are used for the purpose of frequency determination in oscillators, radio receivers, quartz crystals, and other electrical devices. As such, their impact on the performance of these devices remains so crucial.AT-8.000MAPJ-T (AT-8000) is a series of miniature SMD quartz crystals developed by Toko, Inc., a leading supplier of crystals. AT-8000 contains two ceramic-based leadless packages, in either 0.50mm or 0.60mm pitches. It has an excellent storage temperature of - 55 to + 125 degrees Celsius, which makes it suitable for use in harsh environment applications.

AT-8.000MAPJ-T Application Field

For frequency determination and clock generator applications, AT-8000 are typically used as extender crystals or transceiver modules. AT-8000 can be conveniently integrated into any system design, such as a consumer electronic product, communication system, or medical system, and are suitable for operations frequency range of 8 to 80 MHz. AT-8000 models are also available for use in embedded applications and consumer electronics, such as home appliances, automotive control systems, industrial radio data communication products, and consumer audio/video products.

AT-8.000MAPJ-T Working Principle

The AT-8000 contains a dielectric resonator which utilizes a quartz crystal of a known frequency. The crystal, which provides an oscillation frequency of 8 MHz is suspended between two ceramic plates and sealed in an airtight ceramic enclosure. This enclosure allows for a continuous and reliable supply of stable frequency. In addition, this enclosure also facilitates the crystal\'s development of precision, sinusoidal output.

The quartz crystal in the AT-8000 is driven by a unique oscillator circuit which is based on the combined use of Pierce, Colpitts, and Clapp oscillator circuits. The oscillator circuit allows for accurate frequency conversion even when the output frequency changes due to temperature variation, extraneous vibration, or other factors. Additionally, the AT-8000 uses a Transient Model compensation principle in order to reduce the shock of sudden electric currents, providing reliable frequency stability over the entire operating temperature range.

The output signal of the AT-8000 is a sinusoidal wave, which is then adjusted to reduce signal distortion caused by external electric currents. The signal generated by the AT-8000 can also be input into devices such as clock generators, signal converters, telecommunication systems, and digital integrated circuits. Furthermore, the frequency of the signal can also be adjusted according to the application requirements.
