Pin configurable/selectable oscillators provide solutions for numerous timing requirements, where alternatives such as crystal oscillators would find difficulties providing quick and easy solutions. One example of such a product is the 532MB000289DGR, which is designed with the purpose of providing maximum flexibility surrounding output frequencies, features, and costs. This article will provide an overview of the application field and working principle of this type of oscillator.

Application Field

Pin configurable/selectable oscillators are generally used in applications requiring quick, easily adjustable frequency and/or output driver capabilities. This type of oscillator provides flexibility and convenience, enabling users to select solutions that have been tuned to specific needs. The 532MB000289DGR can be used to create a wide range of frequencies, enabling users to construct solutions tailored to their requirements. Examples of application fields that can benefit from the use of this type of oscillator include:

• Computer peripherals
• GPS systems
• Security systems
• Medical equipment
• Communication systems
• Industrial automation systems

Working Principle

At its core, the 532MB000289DGR is a CMOS oscillator that uses the principle of positive feedback and passive elements to generate a stable oscillation. The oscillator utilizes resistors, capacitors, and other passive elements to build a low-frequency and low-phase-noise oscillator, which can then be tuned to a user-specified output frequency.

The 532MB000289DGR also uses a Pin Configurable/Selectable topology. This topology uses a differential tuned LC network and a pair of cross-coupled transistor switches in order to generate the desired output frequency. The LC network is used to create the resonant frequency and the transistors act as the frequency control elements, which can be set and adjusted by the user.

By using an external crystal as a reference, the oscillator can be tuned to the desired frequency. The frequency can then be adjusted by changing the resistance of two or more pins, or selecting one of the two pre-set frequencies from a pair of external components. The design of the oscillator also allows for various output driver configurations, including CMOS, push-pull, dual-open collector, or single-open collector.

Conclusion

The 532MB000289DGR pin configurable/selectable oscillator is designed to provide a flexible and reliable solution for various timing applications. It employs a Pin Configurable/Selectable topology and uses external components to adjust and set the desired output frequency. This makes it an ideal choice for applications that require quick and easy frequency tuning and output driver configurations.
