Crystals are used in a wide range of applications throughout industry and electronics. One such application is the TFA202WG327KR crystal oscillator by TXC Corporation. This device is a SMD (Surface Mount Device) crystal that offers a wide frequency range of 4MHz to 54MHz and is designed to provide a low phase noise oscillator source. This document will discuss the application field and working principle of the TFA202WG327KR crystal oscillator.

Application Field

The TFA202WG327KR is a multi-purpose device that is suitable for many different types of applications. It is usually found in telecoms, networking, instrumentation and industrial applications. It can be used as a clock source in high-end data center equipment or as a frequency reference in test instruments or radio receivers. It can also be used in applications that require high stability and low phase noise, such as high-end time and frequency measurement equipment. In addition, its wide frequency range makes it suitable for a variety of applications.

Working Principle

At its core, the TFA202WG327KR crystal oscillator is based on the same principle as most quartz crystals — it works as an electrical resonator. Inside the device is a quartz crystal that is cut in a way that it will vibrate at its resonant frequency when an alternating current is applied to it. The resonant frequency is determined by the shape and size of the crystal, and produces an accurately timed square wave output. By controlling the shape of the quartz crystal, the size of the device can be reduced, making it an ideal choice for use in SMD equipment.

The oscillation of the quartz crystal creates an alternating current that is then amplified using a transistor. This amplified signal is then fed back to the crystal, causing it to oscillate at its resonant frequency. The output of the oscillator is then sent to the application circuit, where it is used to drive the clock rate of the device. The frequency range of the TFA202WG327KR can be adjusted by changing the frequency of the quartz crystal.

By utilizing the quartz crystal within the TFA202WG327KR, the device is able to generate a highly accurate and stable signal that is useful in a wide range of applications. The wide frequency range makes it suitable for many applications, such as telecoms, networking, instrumentation and industrial applications, and its low phase noise output makes it suitable for applications that require high stability and low phase noise, such as high-end time and frequency measurement equipment.
