Crystals are essential components for many different types of electrical and electronic circuits. CA-301 4.0000M-K: PB FREE is a type of crystal designed for use in a range of applications. This article will explain the applications of the crystal, as well as its working principle.

Crystals of this type have a specified frequency range and are used in many complex circuitry systems. The most common application is in the form of an oscillator, used to convert electrical signals into digital signals. Other applications may include microcontrollers, digital audio systems, and modems. The frequency of the crystal also determines its accuracy, so crystals with higher accuracy may be used in more sensitive applications.

The CA-301 4.0000M-K: PB FREE is a frequency-tuning temperature compensated crystal unit (TCXO). It has a specified frequency range of 3.2MHz to 6.2MHz, with a room-temperature frequency tolerance of ±0.7ppm (parts per million). This crystal has the advantages of low cost, low power consumption and good stability, making it ideal for use in small circuits.

The working principle of the TCXO crystal is based on a phenomenon known as the vibration of quartz. When a quartz crystal is stressed, it vibrates and produces a precise, stable frequency. The characteristics of the crystal determine the frequency range and the frequency accuracy. The temperature coefficient of the crystal affects the accuracy, and to counteract this, a temperature compensation circuit is used to keep the crystal working in its optimal temperature range. This is why the term ‘temperature compensated’ is used for TCXOs. The TCXO crystal unit is typically two quartz crystals, a temperature compensation circuit and a frequency divider in a single package.

The CA-301 4.0000M-K: PB FREE is an ideal crystal choice for various applications. It can be used in automotive devices and medical applications, such as blood glucose monitors. It is also suitable for use in smart meters, digital TV tuners, and mobile communications. In addition, the crystal can be used in a variety of industrial controllers, measuring instruments and other applications requiring precise and reliable frequency control.

In summary, the CA-301 4.0000M-K: PB FREE is a crystal designed for use in a range of applications. It is a temperature compensated crystal unit, which has the advantages of low cost, low power consumption and good stability. The crystal is suitable for automotive devices, medical applications, smart meters and digital TV tuners, as well as other applications requiring precise and reliable frequency control. The working principle of the crystal is based on the vibration of quartz crystals, and the temperature coefficient is compensated by a temperature compensation circuit.
