Crystals

Crystals have been used as part of electronic circuits since early days of radio in the 1940s. In modern electronics, crystals are even more important, appearing in cell phones and other electronic products. The 402F26012IAR is a member of a family of electronically tuned, temperature-compensated crystal clock oscillators that have become widely used in modern electronics, serving as a timing and frequency reference in high-precision, low-power and low-cost applications.The 402F26012IAR is designed to be used as a source of precision clock and timing signals for a wide range of applications. It is used in consumer electronics, wireless or wired communications and automotive systems. A wide range of industries use IARs as timing sources in their product designs.A crystal oscillator, such as the 402F26012IAR, is a circuit consisting of a crystal and associated electronic components that together generate an electrical signal oscillating at a predictable frequency, which can be converted into a time base or into other sequences through external logic. The crystal oscillator oscillates as a result of the piezoelectric nature of quartz crystals, which causes the crystal to vibrate at a specific frequency in response to an electric field.The basic working principle of an IAR is based on an oscillator core which consists of an AC coupled LC tank circuit with an amplifier and a quartz crystal from which a frequency signal is generated. The AC coupled LC tank circuit is formed by an inductor and a capacitor, along with an amplifier. As the current flows through the inductor, a voltage drop is produced, a field is generated and applied to the crystal, resulting in an oscillation frequency determined by the inductor and capacitor.The IAR also includes other components such as frequency selection networks, a frequency-dividing circuit, on-chip temperature compensation networks, output drivers and power detectors. The combination of all these components provides the flexibility to be used in different applications.With the frequency-dividing circuit, the oscillator can be programmed to have different frequencies depending on the desired application. This is why IARs are also known as electronically-tuned clock oscillators, allowing users to change the frequency easily while some other clock oscillators require mechanical tuning.Due to its flexible and reliable performance, the 402F26012IAR has become a popular choice for a wide range of applications. Its small size and low power consumption makes it perfect for portable devices such as smartphones and tablets. Additionally, it is also used in wireless sensors, medical equipment and automotive systems for its ability to maintain high accuracy over a wide temperature range.In conclusion, the 402F26012IAR is a type of electronically tuned, temperature-compensated crystal clock oscillator which is designed to provide precision timing signals for a variety of applications. It can be easily programmed to have a range of frequencies and provides reliable performance in even the most demanding conditions.
