Crystals form an essential component in the implementation and function of many devices in modern technology. Such is the case for the MA-506 24.5760M-C: ROHS Application Field and Working Principle, a type of crystal oscillator popularly utilized in many different industries, fields and applications. This article serves to provide an overview and explanation of the aspects, characteristics and operation of the MA-506 24.5760M-C: ROHS, its applications and its working principle.

Background Information

The MA-506 24.5760M-C oscillator is a type of piezoelectric quartz crystal oscillator as specified by RoHS, the Restriction of Hazardous Substances Directive (also known as Directive 2011/65/EU) from the European Commission, which seeks to restrict the emission of hazardous substances in electrical and electronic equipment. The RoHS compliant MA-506 24.5760M-C offers a wide range of industrial applications with what is typically a very cost-effective product.

This type of oscillator operates off of 24.5760MHz with a ±30ppm stability. It is hermetically sealed in a miniature 5.8xx10.2mm surface mount casing. Besides RoHS compliance, the MA-506 24.5760M-C meets additional regulatory standards, such as that of the FCC, which requires such products to be compliant with their emissions regulations.

Applications

The MA-506 24.5760M-C oscillator finds great usage in many different applications. For example, it is often employed in embedded wireless applications, such as those involving the national infrastructure for cellular or satellite telemetry systems. It is also commonly used to power charging stations, GPS tracking and immersion pumps, in addition to other commercial and industrial applications.

Being a quartz crystal oscillator, the MA-506 24.5760M-C can also find use in a variety of timing and synchronization processes. This includes low-noise analytical systems, power electronics and high-end digital signal processing (DSP) in a variety of communication systems. The applications listed are but a few of many that exist for this type of crystal oscillator, as there are a plethora of opportunities to be explored in the different areas of use.

Working Principle

The working principle of quartz crystal oscillators, such as the MA-506 24.5760M-C, is based on the piezoelectric effect which is the ability of certain materials to generate an electric charge in response to physical stress. For this particular type of oscillator, there is a quartz crystal that is encapsulated between two electrodes and it functions as an ‘active’ material. A driving electric signal current causes the crystal to vibrate at its resonant frequency when this driving force is properly applied by means of an LC (inductor-capacitor) circuit.

Of note is that the frequency of this crystal oscillator also depends on the shape, size and orientation of the crystal. Here too, the application requirements dictate the parameters of the crystal which itself, as a piezoelectric material, is produced and cut to the specified frequency. With the LC circuit, it controls which frequency the crystal oscillates in, while the natural resonant frequency of the quartz crystal itself serves as the basis.

This oscillation can then be employed to generate a signal at the desired frequency, be it analog or digital, amplified or not. This signal can then be tapped off and utilized by any application that requires a clock signal of this specific frequency.

Final Thoughts

In conclusion, the MA-506 24.5760M-C quartz crystal oscillator is a popular RoHS compliant quartz crystal oscillator that can find numerous applications across various industries and technology fields. Its principle of operation is through the piezoelectric effect, whereby a driving electric signal causes the quartz crystal to vibrate at its natural resonant frequency, which is determined by the cut, size and orientation of the crystal itself. With the addition of an LC circuit to control the frequency, this quartz crystal oscillator is capable of producing an analog or digital, amplified or non-amplified signal as required to fulfill application requirements.
