Oscillators: 579R200CAT Application Field and Working Principle
The 579R200CAT is a crystal oscillator module that provides stable and dependable frequency reference. This device is suitable for use in a variety of applications requiring reliable and consistent frequency sources. Generally, it is used in generating the reference frequency for computer motherboards, communications devices, security systems, and other electronic systems, as well as in generating the high-frequency signal for loudspeakers or any other audio-related activities. This article will discuss the application field and working principle of the 579R200CAT crystal oscillator.

The 579R200CAT crystal oscillator has a wide range of applications due to its stable frequency and low-noise performance. This device can serve as an oscillator in frequency synthesizers, where the stable reference frequency provided by the 579R200CAT is essential in order for the synthesized signal to be accurately mapped to the desired frequency. Additionally, this device can be used to generate a clock at a specific frequency accurate to parts-per-million, which is beneficial for Ethernet communications devices and other digital communications systems requiring exact arithmetic computations. Moreover, due to its low-noise characteristics, the 579R200CAT module is also suitable for use in systems that require highly sensitive frequency measurements such as nuclear magnetic resonance (NMR) instruments, radar, and high data-rate communication systems.

The 579R200CAT crystal oscillator has a three-terminal connection and consists of an oscillator circuitry and amplification circuit that communicates with the microcontroller or digital circuit. The oscillator functionality is achieved by the external quartz crystal, which serves as the frequency stabilized reference, while the amplification input circuit produces an output voltage across its terminals that can be used to control the frequency of the oscillator. The oscillator must be tuned with an external resistance, which is generally done using an RC filter or LC filter. The amplifier, on the other hand, is intended to control the gain of the output voltage and attenuate noise to a minimum.

Overall, the 579R200CAT crystal oscillator is a reliable frequency reference with a wide range of applications. The device can be used for digital communication systems, frequency synthesis, and frequency measurements that require the utmost accuracy. Furthermore, the 579R200CAT is a three-terminal device that includes an oscillator and amplifier circuit that communicates with the microcontroller or digital circuit. To work, the device must be tuned with an external resistance, which ensures the crystal oscillator provides a stable frequency reference used in the application.
