8Z-38.400MAAJ-T Crystals, Oscillators, Resonators

Crystals

Crystals are the basic physical building blocks for all electrical and electronic products. Without crystals, these products would become useless. One such product is the 8Z-38.400MAAJ-T crystal.

Application Field and Working Principle

8Z-38.400MAAJ-T is a commonly used crystal, most commonly used in radio communications and toys because of its low cost. Nominally this crystal is 38.400 MHz, and is typically used to create stable clocks in computers, radios, and peripheral devices. The 8Z-38.400MAAJ-T crystal is a quartz crystal oscillator that uses the mechanical resonance of a vibrating quartz crystal to create a signal with very precise frequency.

The 8Z-38.400MAAJ-T crystal is a surface mounted crystal which is small, measuring only 2.5mm x 1.2mm, making it ideal for use in circuit boards with small footprints. It operates over a temperature range of -30 to +85 °C, making it suitable for most electronic applications and also provides a frequency stability of ± 20 ppm over that temperature range.

The 8Z-38.400MAAJ-T is designed to generate an output signal at a precise frequency of 38.400 MHz. The frequency is accurate to within ± 20 ppm over a temperature range of -30 to +85 °C. To generate the signal, the crystal interacts with an external one-turn loop antenna that surrounds the crystal and is connected to ground.

The oscillator works by creating an electric field in the crystal when an oscillating voltage signal is applied to it. The signal oscillates back and forth across the crystal and creates a mechanical resonance in it which generates a frequency that is determined by the parameters of the crystal. As the signal makes its way back and forth across the crystal, it is reflected off the edges of the crystal and is amplified, creating a signal at the desired frequency of 38.400 MHz.

The 8Z-38.400MAAJ-T crystal is often used in consumer electronics such as televisions, radios, and toys. It is also used in medical devices, satellite communications systems, and other industrial applications where precise timing is necessary.
