Crystals

Crystals are physical objects containing regular, ordered arrangements of atoms, molecules and ions. Crystals can be found in solid, liquid and gas form. In general, the structure of a crystal contains interlocking patterns of atoms, molecules and ions arranged in a regular and symmetrical arrangement. Crystals that contain more than one type of substance are known as composites.

LFXTAL012313REEL Application Field and Working Principle

The LFXTAL012313REEL is a cryogenically packaged, hermetically sealed, line-replaceable unit (LRU) quartz crystal designed for use in very low temperature applications where high accuracy and reliability of frequency control is essential. The device is compatible with a wide range of commercial containers and can be operated in hostile environments where exposure to wide temperature extremes, shock, and vibration are potential hazards. The LFXTAL012313REEL utilizes a unique hermetic sealing process that ensures that the crystal is totally encapsulated and prevented from moisture and corrosion caused by direct contact with the environment.

The working principle of the LFXTAL012313REEL is based on the crystalline structure of its piezoelectric material, which serves as the oscillator medium. When an alternating electric current passes through the crystal, the material experiences a force that causes it to change shape. The force is proportional to the magnitude of the electrical current, and once a steady-state electrical signal is established, the crystal will start to oscillate at a precisely-defined frequency. In relation to its voltage-dissipation characteristics, an LFXTAL012313REEL is designed to be a low-power device, making it suitable for low-voltage applications.

The LFXTAL012313REEL also features an impedance matching circuit, which prevents harmonic distortion of the output signal while ensuring that the signal amplitude remains consistent. This impedance matching circuit also allows the crystal to be used in applications where the signal levels are subject to large changes.

The LFXTAL012313REEL is a versatile device that has multiple applications, including telecommunications systems, process control systems, microwave and microprocessor-based systems, and test and measurement systems. In addition to these, the device can also be used in medical and military systems where high accuracy and reliability of frequency control is essential.
