Crystals are well-known for their various applications in many fields, including high-precision timing, frequency control, high-end oscillators and more. Formally, a crystal is a piezoelectric material made of certain materials, and when a voltage is applied to it, its physical properties change accordingly. 8Y-27.000MAAE-T is a crystal within the 8Y series from ETC, and this article will cover its key application field and working principle.

The 8Y-27.000MAAE-T crystal has a variety of applications, including in oven controlled oscillators (OCXOs). This type of oscillator uses the crystal\'s properties to generate a precise frequency, which is necessary for many functions such as scientific instruments and medical equipment. The 8Y-27.000MAAE-T crystal also has a much broader application field as it includes high-end oscillators such as VCXOs, TCXOs, and MCXOs among others.

The 8Y-27.000MAAE-T crystal is an AT-cut crystal made of silicon. It is built with a simple resonator structure, which consists of a capacitive plate and metallic electrodes, connected by electrodes to form an oscillation loop. AT-cut crystals have a higher oscillatory stability due to the resonance frequency being closer to the desired frequency. The 8Y-27.000MAAE-T has a particularly low frequency-startup, making it more suitable for oscillators that require a high starting frequency.

When a voltage applied to the 8Y-27.000MAAE-T crystal, the piezoelectric effect is triggered. The piezoelectric effect is the physical effect whereby an applied electrical field will cause the crystal\'s physical structure to vibrate and generate an output electrical signal. This output signal is used as the oscillatory frequency reference for the oscillator. The oscillator then amplifies this signal and raises it to the level of its output frequency.

The 8Y-27.000MAAE-T crystal also comes with several extra features that make it a power-hungry crystal. It has a very low ESR (Equivalent Series Resistance) of 12-Ohm, as well as a low-power voltage range of 0.5V – 5.5V. This makes it more suitable for battery operated applications, as it can run at lower power levels. Moreover, the 8Y-27.000MAAE-T also has a high shock stability of 1G, which helps maintain a high accuracy of the frequency output. This makes it suitable for rough-environment applications such as automobiles.

In conclusion, the 8Y-27.000MAAE-T crystal from ETC is an incredibly versatile product, with a broad range of applications. It is specially designed for low-power applications, such as battery operated devices, by providing an ultra-low ESR and a high voltage range. Additionally, it also has a high shock stability, making it suitable for the most demanding applications. As such, the 8Y-27.000MAAE-T crystal is a great choice for any researcher or engineer in the field of timing and frequency control.
