Crystals have a wide range of uses in electronics, including computer oscillators, transmitters, and receivers. The ATS250B crystal is a precision quartz crystal used in high-stability oscillator circuits. It is designed to provide a high accuracy, low temperature coefficient, and drivability. This article will discuss the applications and working principle of the ATS250B crystal.

The ATS250B crystal is suitable for use in applications such as radio communications, data transmission and reception, digital modulation/demodulation, clock and timing circuits, as well as amplifier and mixer circuits. Additionally, it is widely used in systems that require tight temperature stability, such as spacecraft, satellites, and GPS systems. The ATS250B crystal is compact, highly reliable, and low-power.

The quartz crystal is the basic building block of oscillators and timing circuits, and the ATS250B crystal is a precision quartz crystal featuring both high stability and high accuracy. It features a low temperature coefficient, typically 0.25ppm/°C, and can be tailored to specific oscillation frequencies ranging from 1MHz to 50MHz. The ATS250B also has a low-power consumption of 7 - 10µmW, making it an ideal choice for applications that need to conserve power usage. Additionally, the crystal is designed to be a "push-pull" oscillator, providing a high level of stability and accuracy.

How does the ATS250B crystal work? When operated in a series mode, the crystal acts as the frequency-determining element of the oscillator circuit. The crystal is composed of quartz with a piezoelectric effect. When an alternating voltage is applied to the quartz, it produces a mechanical strain that causes the quartz to vibrate at a particular frequency. This mechanical vibration also generates an electrical current, which is called the oscillator’s output. The frequency of the oscillation is determined by the physical characteristics of the quartz itself.

When the ATS250B crystal is used in a parallel mode, it is combined with a capacitor to form a resonator. This configuration increases the resonance frequency of the oscillator circuit and improves the stability of the oscillator. In a parallel mode, the ATS250B’s resistance is much higher than its inductance, which improves the drivability of the oscillator.

The ATS250B crystal is also designed to be a low-noise device. The crystal has a very low phase noise, which eliminates the need for shielding in many applications and eliminates any potential for unwanted interference. Additionally, the crystal features a high Q-factor, which increases the accuracy of the oscillator.

The ATS250B crystal is a reliable and accurate device that is suitable for use in a wide range of applications. The crystal is designed to provide a high level of stability, accuracy, and drivability, while consuming low power. It is also designed to be a low-noise device, eliminating the need for shielding in many applications and helping to ensure accurate clock frequencies and timing.
