Crystals – CA-301 49.5400M-K: PB FREE Application Field and Working Principle

Crystals are electrical components used to create and regulate the frequency of current or voltage that flow from one device to another. This allows for certain electronics and applications to work accurately, at fast speeds and with a high degree of accuracy. The CA-301 49.5400M-K is a type of crystal commonly used in Personal Computers (PCs) that have PB FREE and integrates the field of High Speed Crystal Oscillators (HSYOs).

Application Field

The CA-301 49.5400M-K crystal is ideally suited for use in PB-FREE (Polychlorinated Biphenyl-Free) personal computers, laptops, notebooks and other consumer electronic devices. The highly reliable and cost-effective crystals feature quick start-up times and excellent frequency stability. The crystals come in a 3.2 x 2.5mm package, making them ideal for space-restricted PCB design.

Working Principle

The CA-301 49.5400M-K crystal works by using the property of piezoelectricity in which electrical energy is generated when a quartz crystal is mechanically stressed. This energy can then be used to generate an oscillator circuit, which produces a consistent frequency.The working principle for the crystal consists of three main elements: a quartz crystal resonator, an amplifier, and a feedback resistor.The crystal resonator is the heart of the oscillator, and it consists of a quartz crystal and two electrodes. When a positive potential is placed on one electrode and a negative potential is placed on the other, an electrical signal is generated. This signal is then amplified by the amplifier, and the resulting signal is fed back to the quartz crystal after passing through the feedback resistor.The signal is then reflected back to the quartz crystal, causing it to vibrate at a consistent frequency. This frequency is determined by the cut angle of the crystal, which sets the frequency at a specific point. The higher the frequency, the higher the output power of the oscillator, which can be set to any desired value with the appropriate feedback resistor.

Conclusion

The CA-301 49.5400M-K crystal is a powerful, efficient and cost-effective option for various kinds of consumer electronic applications that require highly reliable and stable frequency outputs. The crystals come in a space-saving 3.2 x 2.5mm package and use the property of piezoelectricity to generate an oscillator circuit with a consistent frequency for quick start-up times and efficient operation.
