Crystals: NX1255GB-12.288000MHZ application field and working principle

Crystals are one of the most commonly used components in electronics. Ironically, despite their ubiquity and fundamental importance, many people do not understand the basic principles behind crystals and their use in different applications. This article will look at NX1255GB-12.288000MHZ, a quartz crystal typically used in consumer electronics, and examine its applications, working principle and design considerations.

Applications

NX1255GB-12.288000MHZ crystals can be found in a variety of consumer electronics, from audio equipment and watches to various types of communication and control systems. This type of crystal is ideal for devices that require precise frequency and timing such as oscillators and clocks, as it can provide an accurate and stable output. Depending on the application, these crystals can be used as the main or sub-clock in a circuit, or as an ultra-precise timer.

Working Principle

NX1255GB-12.288000MHZ crystals are quartz crystals, constructed by etching microscopic features into a thin quartz substrate. When an electric current is applied to the crystal, it alters its shape and creates a mechanical vibration at a precise frequency. This frequency can range from a few kHz to several hundred MHz and is determined by the size and shape of the etched features. In addition to the precise frequency, these crystals have extremely low jitter and low phase noise, making them ideal for high-precision timing applications.

Design Considerations for Using NX1255GB-12.288000MHZ Crystals

When designing a system that uses NX1255GB-12.288000MHZ crystals, several important design considerations must be taken into account. First and foremost, the system must be designed to provide the correct power supply voltage (Vdd). The crystal requires a precise voltage to function properly and if the supply voltage is too low or too high, the crystal will not produce the correct frequency or amplitude.The circuit also needs to provide the proper load capacitance to the crystal. XTAL load capacitance greatly influences the crystal’s output frequency. Too little load capacitance will significantly reduce the oscillation frequency, while too much capacitance will increase the frequency and introduce phase noise and jitter.Finally, the board design must provide sufficient decoupling capacitors to prevent noise and voltage fluctuations from reaching the crystal. The decoupling capacitors help to reduce power supply noise and also provide a consistent power supply voltage to the crystal.

Conclusion

NX1255GB-12.288000MHZ is a quartz crystal commonly used in consumer electronics. It has a highly precise output frequency, low jitter and low phase noise, making it ideal for applications that require precise timing and frequency. When designing a system that uses this type of crystal, the power supply voltage, load capacitance and decoupling capacitors must be taken into account in order to ensure the crystal functions properly and produces a stable output.
