Introduction

Crystals are among the oldest and most widely used materials in the world, formed by the organized union of atoms that own distinct properties giving them unique geometric shapes and producing frequencies when exposed to electricity. Among the diversity of crystals can be found the 9B-22.000MAAJ-B crystal.

9B-22.000MAAJ-B

The 9B-22.000MAAJ-B is a high precision and high stability crystal with a low-aging feature and is ideal for applications in low-noise and low-drift environments. This particular crystal is designed for industrial applications such as temperature monitoring and precision clock oscillators, and works best in frequencies ranging from 20 kHz to 40 MHz. This crystal offers a reliable frequency accuracy over temperature and vibration due to its high Q factor which provides operations with minimal jitter, making it the favored choice to build effective, stable and long-lasting applications.

Application field

The 9B-22.000MAAJ-B crystal is mainly used as a base of precision clock oscillators in different industrial fields, given its capacity to maintain low-noise and accurate frequency in the face of different temperature or vibration conditions. This device can be applied in sectors like industrial automation, test and measurement, communications and IoT sensing with the purpose of providing long-lasting stability activities in its field of application.When talking about the industrial sector, the 9B-22.000MAAJ-B crystal is a natural choice for automotive control modules and ECUs, aerospace systems and electronic instrumentation where precision timing and accuracy is a must. It is also used for radio base stations as a reference clock for the frequency synthesizers, providing fast and linear PLLs, even in harsh environmental conditions.Another interesting feature of this crystal is that is quite the preferred choice for embedded systems and battery powered applications, since it consumes very little energy and ensures a controlled output frequency for lengthy periods of time.

Working Principle

The 9B-22.000MAAJ-B crystal works under a basic principle of quartz vibrators which is the piezoelectric effect. This peculiar property produces oscillations within the crystal when it is exposed to electrical power, with these oscillations having a specific frequency depending of the crystal’s parameters. The 9B-22.000MAAJ-B crystal specifically works by providing very small current pulses to the quartz vibrator at regular intervals, creating the necessary oscillations to produce the frequency. The device is built with a temperature compensated oscillator (TCXO) that helps keeping the oscillations maintained over wide temperature ranges, and with a low-aging feature that keeps accuracy even after long periods of time.Its output can be adjusted to a wide range of frequencies and from 5 to 40 Mhz with a series of external components and adjustments, with the same transistors delivering low-noise and low-drift performance over long periods.

Conclusion

Overall, the 9B-22.000MAAJ-B crystal is an ergonomic and reliable device meant for industrial and embedded applications in sectors where precision, accuracy and low reaction time to temperature and vibration variations is required. This device provides the necessary frequency accuracy and power efficiency for many projects that require long-lasting stability and performance.
