Crystals are physical objects made from pure crystalline materials with electrical or optical properties. Crystals can be used to transmit, detect, amplify and store energy. Electro-optical components and devices use the electrical and optical properties of crystals to perform their various functions. The FC-12M 32.7680KA-VJ is one type of crystal that has a range of applications and a number of working principles.
The FC-12M 32.7680KA-VJ is a single-axis, thermally compensated crystal of the OCXO (Oven Controlled Crystal Oscillator) family. It is designed specifically to provide precise, stable performance over a wide range of operating temperatures. This makes it suitable for use in aeronautics, telecommunications and GPS navigation applications, where low jitter is imperative. The frequency stability of this crystal is within 0.2ppb over a temperature range of -40 ˚C to +125 ˚C. It also has an excellent frequency accuracy of ± 0.04ppm.
The FC-12M 32.7680KA-VJ crystal uses a Quartz AT cut design, whereby two surfaces of the crystalline material are cut at an angle of 30 degrees. This angle is specifically tailored for a range of frequencies between 8MHz and 125MHz. The crystal is vibrated through the application of an AC voltage, usually between 5V and 15V. This vibration is known as the piezo-electric effect and it is used to generate an alternating electrical current, which is then used to clock on-chip components.
The FC-12M 32.7680KA-VJ also employs a thermal compensation mechanism, known as “thermo-compensation”. This works by directly sensing temperature changes, rather than relying on an electrical indicator, such as a thermistor. This ensures that it maintains highly precise and stable frequency control over a wide range of temperatures. In addition, the crystal incorporates piezoelectricity and thermoelectric effects to reduce the influence of temperature change. This results in excellent frequency stability and accuracy, even at extreme temperatures.
The FC-12M 32.7680KA-VJ crystal is an ideal choice for precision timing applications. It can further be used in the development of radio transmitters and receivers, microwave amplifiers, frequency synthesizers, GPS systems and digital data transmission systems. It is an especially suitable choice for applications where precise, low jitter frequency control is required. As premium crystal components, the FC-12M 32.7680KA-VJ is also ideal for vibration-sensitive projects, such as for test and measurement instruments.
The FC-12M 32.7680KA-VJ is a highly useful crystal for a range of applications that require ultra-precise frequency control and accuracy. It incorporates a number of valuable features to ensure superior performance in the toughest of conditions over a wide range of temperatures. By using the piezoelectric and thermoelectric effects, it is able to provide excellent frequency stability and accuracy for a number of critical applications.
Crystals are a fundamental part of modern electronics and the FC-12M 32.7680KA-VJ is a prime example of what they can do. By leveraging the vibrational properties of its crystal structure, this type of crystal is able to provide an exceptionally precise frequency over a wide range of temperatures. This makes it an invaluable tool for applications that require high precision and accuracy.
