Crystals have found widespread applications in many fields since early days, LP260F35CDT being one of those crystals that have seen extensive use. This crystal, made from the piezoelectric material LiNbO₃, is optimized for use in digital converters for data transmission and clocking of digital devices due mainly to its low power consumption.

LP260F35CDT crystals offer superior performance over traditional crystals, such as quartz and paratellurite, due to their high frequency performance and low power requirement. Their frequency performance is between 8 MHz and 25 MHz and they operate on 1.6V power, making them ideal for use in portable devices such as mobile phones and other wireless devices.

LP260F35CDT is most suited for applications such as clock cycles, where they provide a stable and efficient source of clocking. They are also increasingly used in communication systems, where they are kept in oscillation to provide a stable time base. Additionally, LP260F35CDT crystals are also used in a host of other digital and analog applications, ranging from D/A and A/D converters to timers and frequency synthesizers.

Like all crystals, the LP260F35CDT works by using a piezoelectric material. Piezoelectricity is the ability of certain materials to create a voltage when physically deformed. The LP260F35CDT crystal is a combination of LiNbO₃ and LiTaO₃) material in a layer structure.

When the voltage is applied to one of the electrodes, the material deforms and creates mechanical stress. The mechanical stress causes an angular distortion of the crystal lattice, and due to the piezoelectric effect, a transverse electric field is created within the crystal. This electric field causes a strain in the crystal’s lattice, which in turn produces a charge imbalance across the crystal. This charge imbalance induces a net electric dipole moment and produces a net electric field.

The presence of this electric field stimulates the mechanical vibration of the crystal, which then oscillates at its resonant frequency. This frequency is determined by the physical dimensions of the crystal, which are dependent on the application. The frequency of resonant vibration is highly stable and is used to control the electronic clock cycles and the precision of data delivery in communications systems.

The LP260F35CDT crystal, due to its high frequency performance, low power requirement, and low noise (<19 dB), is ideal for use in such digital, as well as analog, applications. Recent advances in the miniaturization of this device have further boosted its utility, making it the preferred choice for applications requiring high frequency stability.
