Crystals, have been integral components of electrical designs since the mid 20th century, when engineers began to apply them for specific tasks where frequencies were concerned. Admired for their reliability, budget, and accuracy to a fault, quartz crystals are used today in a variety of applications, including, but not limited to: watch and clock movements, frequency generation, and timing. However, in the modern world of electronic engineering and computer science, quartz crystals are often associated with their application within oscillators and resonators alike.To understand their application within modern circuits, it’s important to understand the differences between an oscillator and a resonator, as well as how each utilise quartz crystals. An oscillator is an electronic circuit that produces an unstable (or sustained) acoustical, electrical, or optical output signal which is used as an input signal to another circuit. A resonator, on the other hand, is a circuit where the output signal of an oscillator interacts with a filter to produce periodic amplitudes at the input frequency of the filter. In this sense, a resonator can be seen as a frequency selector, as the input signal of the oscillator is forced to interact to specific frequencies.The ATS25A is a high-precision manufacturer of quartz crystal oscillators built using the latest state-of-the-art electronic manufacturing technology. It is commonly used in electronic and nuclear engineering applications, allowing for precise signal generation within cascaded harmonic oscillator circuits.The ATS25A operates on several different principles, but is mainly driven by a quartz oscillator which is located in the center of the device. The oscillator produces a frequency signal which is fed into two separate systems: an internal amplifier, and an external resonator circuit. The internal amplifier increases the frequency and amplitude of the signal before it is passed to the external resonator circuit. This resonator serves as the frequency selector, limiting the signal to only frequencies within a predetermined range.The most important feature of the ATS25A is its accuracy and reliability, as it uses a highly calibrated PLL integrated circuit to ensure the attenuation and amplification of the signal is done within specified tolerances. This is done by constantly monitoring the feedback signal of the resonator and making small adjustments to the signal so that it is outputted within the predetermined range.The overall stability of the ATS25A is further enhanced by a proprietary technology developed by the manufacturer called the "noise reduction circuit", which reduces the amount of harmonics that accompany the signal and ensures a higher level of signal purity. This circuit includes a low-pass filter and active or passive dampening elements which prevent unwanted high-frequency signals from distorting the oscillator signal.Overall, the ATS25A is an extremely reliable quartz crystal oscillator, offering precise signal generation and frequency stabilization. Its combination of precision engineering, advanced noise reduction circuit, and superior temperature compensation provides a superior level of performance and accuracy, perfect for highly specialized frequency-sensitive applications.
