LFXTAL009709REEL

Crystals are man-made devices that are capable of accurately converting electrical energy or signals to radio frequencies for wireless communication. They are used in various applications, including radio frequency (RF) transmission, data and signal processing, time-keeping and oscillators. The LFXTAL009709REEL is a special type of crystal, characterized by its low power consumption, insensitively to vibrations and excellent thermal stability.

Application Field

The LFXTAL009709REEL crystal is mainly used in different consumer applications and consumer electronics in order to support standard communication protocols such as Bluetooth, Wi-Fi a/b/g/n, and ZigBee. It is also used in low-cost wireless communication modules that require low power consumption when operating. It is designed for applications such as AM and FM Receivers, Compact Disc Digital Audio (CD-DA), computer peripherals, set-top boxes, mobile phones, and digital still cameras.

Working Principle

The LFXTAL009709REEL crystal works on the principle of Ferro-electricity. This is a type of thermal effect which occurs when a material undergoes a change in electrical polarization at a certain temperature. In the case of the LFXTAL009709REEL crystal, it forms an electric dipole in response to an applied voltage. When a voltage is applied, the oscillation frequency of the dipole changes; this is perceived as an output signal.

The LFXTAL009709REEL crystal is designed with a certain value of load capacitance, which is the capacitance that must be applied to the crystal in order to achieve the desired frequency. The frequency of the output oscillations is determined by the value of the load capacitance, the quartz element and its geometry. The crystal also contains an air-capacitance that is used in high-precision applications to maintain the crystal\'s accuracy over a wide temperature range.

To ensure that the crystal works within its specified frequency range, it is important to select a crystal with the correct loading capacitance for the application. The optimal value for the loading capacitance depends on the operating temperature. Too small a value may cause the crystal to operate outside of its specified frequency range, while too large a value may cause decreased oscillation frequency stability.
