Crystals

Crystals are used in a wide range of applications, providing essential timing components in many electronic products. Different types of crystals are used for different applications and the NX3215SA-32.768K-STD-MUA-14 crystal is one of the most popular crystals for timing use. This article will focus on discussing the application fields and working principle of this crystal.

Application Field

The NX3215SA-32.768K-STD-MUA-14 crystal is a standard crystal oscillator typically used in real time clock and clock generator designs. It is well-suited for low power applications and is typically used for microcontrollers, calculators, embedded systems and other digital electronics that require precision timing. The crystal can also be used in five lead ceramic packages in applications such as watches and multimedia equipment.

The NX3215SA-32.768K-STD-MUA-14 crystal features a low power consumption of no more than 300nA and a frequency stability of ±25ppm over Temperature (-20°C to 70°C). It is designed to operate at a frequency of 32.768kHz and a temperature of -20°C to 70°C. The crystal also offers wide uncompensated frequency range of 32.000kHz to 33.000kHz and most importantly, is RoHS compliant.

The crystal is ideally suited for use in real-time clocks in digital applications such as computers, televisions and communication systems. Its low power consumption and high frequency accuracy make it especially well suited for use in battery-powered applications, where power consumption must be kept to a minimum. The crystal is also suitable for use in embedded systems and microprocessors where timing accuracy and low power consumption are important.

Working Principle

The NX3215SA-32.768K-STD-MUA-14 crystal is an oscillating device that produces an alternating current signal. The crystal consists of a quartz crystal in which two electrodes are embedded. The quartz crystal acts as an electrical conductor, while the two electrodes are used to apply an alternating electrical signal. When an alternating electrical signal is applied to the two electrodes, the quartz crystal vibrates and produces an oscillating current that can be used as a clock signal or as a source of timing information.

The alternating electrical signal applied to the two electrodes causes the quartz crystal to vibrate in a specific way, causing it to create a frequency of 32.768KHz. The frequency can be adjusted by tweaking the electrodes, so that a more accurate signal can be produced. The accuracy of the frequency produced by the crystal depends on the quality of the quartz crystal and the way in which it is cut.

The NX3215SA-32.768K-STD-MUA-14 crystal is a low power and high accuracy crystal oscillator suitable for use in many applications that require precise timing. It is well-suited for battery-powered applications and embedded systems and is ideal for use in real-time clocks and clock generators.
