Crystals are objects with a regular arrangement of atoms and molecules that allow frequencies to be transmitted in oscillations. In this article, we will discuss the application field and working principle of the HCM496144000ABJT crystal oscillator. Crystal oscillators come in many sizes and are used for different purposes, so we will focus on the specific features of this model.

Application field

The HCM496144000ABJT crystal oscillator is designed for use in different applications where precise and stable frequency oscillations are required. It can be used in electronics projects and gadgets, from radios and TVs to digital energy meters and frequency counters. It is also suitable for use in medical monitoring systems and other instruments that need accurate timekeeping such as watches, clocks and time servers. Additionally, the HCM496144000ABJT crystal oscillator can be used in telecommunications and communication equipment, GPS receivers and tracking systems, as well as computers and other electronic devices.

Working principle

Crystal oscillators work by converting electrical energy into mechanical vibration, using a device known as a piezoelectric crystal. This crystal is made up of two pieces of quartz that are electrically polarized and connected to two plates. When a electric current is applied to the crystal, it vibrates and produces electric pulses that can be used to derive consistent oscillations. The frequency of these oscillations is determined by the characteristics of the piezoelectric crystal, as well as by external factors such as temperature and electric fields. In the case of the HCM496144000ABJT crystal oscillator, it has an operating frequency of 12.8 MHz and a temperature stability of ±20 ppm.

The frequency output of the crystal oscillator is determined by the mechanical properties of the piezoelectric crystal. The crystal consists of two plates and a thin slab of quartz crystal between them, known as the “active element”. This active element is held in place by two metal electrodes, which are connected to a circuit that supplies power. When electrical current passes through this circuit, it causes the quartz to vibrate, resulting in a series of electrical pulses that correspond to specific frequencies.

The frequency of the oscillation is determined by the thickness of the quartz crystal and the shape of the electrodes, which act as resonators. The frequency is also affected by external factors such as temperature, which shifts the frequency higher or lower depending on its value. The HCM496144000ABJT crystal oscillator has a frequency stability of ±20 ppm, meaning the frequency will stay within a 20 parts-per-million range of the desired frequency or oscillation rate.

Conclusion

In conclusion, the HCM496144000ABJT crystal oscillator is designed for use in a wide range of applications requiring high precision and stability. It utilizes a piezoelectric crystal to convert electrical energy into mechanical vibration, producing electric pulses with a specific frequency. This frequency is determined by the characteristics of the crystal and is affected by external factors such as temperature. The HCM496144000ABJT crystal oscillator has a frequency stability of ±20 ppm and an operating frequency of 12.8 MHz.
