Crystals

Crystals are widely used as components to control or generate electrical signals or as oscillators in many types of electronic circuits and systems. Quartz crystals, with their strong piezoelectric properties, are among the most commonly used and versatile crystals.

CX49GFNB16000H0PESZZ application field and working principle

CX49GFNB16000H0PESZZ is a quartz crystal unit developed by Chengxing, with a nominal frequency of 16MHz and a frequency tolerance of ±20ppm. It is widely used in 3C (computer, communication, consumer electronics) field and has entered into many industries and products, from simple consumer electronics to nuclear energy instrumentation.

The working principle of Crystal is based on the phenomenon of piezoelectricity of quartz. The piezoelectricity of quartz is a property that enables quartz to generate an electric charge when it is subjected to mechanical pressure. An electric field is generated when a voltage is applied to the quartz, resulting in a mechanical displacement. When an alternating electric field is applied to the quartz crystal, quartz crystal prepares an alternating electric field, and when this alternate electric field reaches a certain magintude, the quartz crystal will vibrate mechanically with a natural resonance frequency.

The frequency of a crystal, also known as its resonance frequency, can be adjusted slightly by changing the shape of the quartz, by changing the size of the crystal, by changing the cut angle, between the X-axis and Z-axis of the quartz wafer, and by providing a certain positive or negative temperature coefficient.

CX49GFNB16000H0PESZZ, with a nominal frequency of 16MHz, provides a high frequency stability, even on the low voltage condition, owing to its high quality cutting and advanced aging technology.

In addition to an oscillator, CX49GFNB16000H0PESZZ also works as a frequency discriminator, voltage regulator and accurate timekeeper. It is also used in seismic and acoustic transducers, speed scanning circuits, radar systems and telecommunication equipment, among other applications. It is a vibration type sensing element, and a versatile electronic device used for various electronic systems.
