Crystals: LP122F35IDT Application Field and Working Principle Crystals, or piezoelectric crystals, are ceramic materials that vibrate at their resonance frequency when an alternating current (AC) is applied. Piezoelectric crystals are used as high-frequency time bases and as filters in audio applications. A piezoelectric material, as the name implies, produces an electric charge in response to mechanical strain or vibration. A crystal unit contains a resonant quartz crystal cut in a particular shape and mounted in an appropriate holder. The LP122F35IDT, available from Diodes Incorporated, is a programmable crystal that provides precision, stability, excellent long-term performance, and temperature tracking over an extended temperature range.The LP122F35IDT is primarily targeted for use in communications, chemical and instrumentation systems, too. It is especially suitable for frequency control applications. The LP122F35IDT is a high-quality and cost-competitive quartz crystal designed with a 32.768 kHz frequency and low ESR (Equivalent Series Resistance) of 2-kΩ at 25°C. This LP122F35IDT unit is designed to function reliably in both military and commercial temperature ranges (-40°C to +125°C).LP122F35IDT is a two-pad crystal unit, usually used to implement a clock signal or to control the frequency of a radio transmitter or receiver. The crystal consists of quartz material which when electrically stimulated produces an oscillatory signal at its resonant frequency. The LP122F35IDT features include a frequency stability of ±20 ppm over the full temperature range of -40°C to +125°C, excellent low ESR of 2-kΩ at 25°C, delta temperature tolerance according to V CC , excellent aging properties, ultra low power consumption, faster frequency settling time and repetitive shock resistance.The LP122F35IDT working principle is based on the piezoelectric effect. The piezoelectric effect occurs when a quartz crystal is placed under mechanical strain. As a result of the strain, an electric charge is created, which results in an electric potential being applied to the quartz crystal. The crystal then starts to oscillate at its resonant frequency due to the application of the electric potential. This oscillation is referred to as the piezoelectric effect. The LP122F35IDT design incorporates a quartz crystal cut in a specific shape and mounted on an appropriate holder that allows it to vibrate in a specific manner.The LP122F35IDT is a great choice for applications that demand good frequency control characteristics. Because the crystal oscillator is hermetically sealed and does not require any power supply, its frequency is very stable and does not vary with temperature changes. Additionally, it offers excellent long-term performance. As such, it is often used as a frequency reference in various applications such as wireless communications, chemical & instrumentation systems, automotive electronics and medical equipments.Aside from being used in communications, the LP122F35IDT can also be employed in automotive and industrial applications. It provides optimal performance in a wide range of products. For instance, quartz crystals are found in a variety of automotive applications, such as car alarms and digital compasses. It is also used in industrial process controllers and sensors.
