Pin Configurable/Selectable Oscillators

Pin Configurable or Selectable Oscillators are oscillators that contain a device that can be programmed to output a desired frequency over a wide variety. This type of oscillator is fundamentally more versatile than typical fixed-frequency oscillators, as different frequencies may be selected with ease. One example of this type of oscillator is the 552AJ000366DGR.

Application Field for 552AJ000366DGR

The 552AJ000366DGR is a crystal oscillator, meaning that it is based on the resonance of a quartz crystal. It is designed to provide frequencies between 1 MHz and 200 MHz, in 1 kHz steps. It is a particularly useful oscillator due to its frequency range and programming capabilities. In addition to its wide range of frequency options, it also offers low phase noise and extremely low jitter.This oscillator is most commonly used in communication devices, such as radios and transmitters. It can be used in many different applications, such as frequency synthesisers, radar systems, navigation systems, digital receivers, and a variety of other fields. Additionally, the 552AJ000366DGR is suitable for applications that require high frequency accuracy and stability, as the crystal oscillator is able to maintain a very accurate and stable frequency even over a wide range of temperatures and environmental conditions.

Working Principle of 552AJ000366DGR

The fundamental working principle of the 552AJ000366DGR is based on the resonance of a quartz crystal. Quartz is an electrostrictive material, meaning that it will deform under an applied electric field. This deformation causes microvibrations which in turn cause resonance at a certain frequency. This is the basic principle of the crystal oscillator. When a voltage is applied to the quartz crystal, it will vibrate at its resonant frequency, allowing it to generate a stable, accurate output frequency.In order to change the frequency of the oscillator, a pin configurable method is used. This method involves programming the device with a digital code which determines the resonant frequency of the device. This code is programmed by applying a voltage to the input pins of the oscillator. Once the code has been successfully programmed, the device will output a stable frequency based on the resonant frequency of the quartz crystal.The 552AJ000366DGR has the advantage of being able to store multiple frequencies in its memory, allowing for multiple frequencies to be quickly switched between as needed. This feature makes the 552AJ000366DGR ideal for applications where multiple frequencies are required and where rapid frequency changes are necessary.

Conclusion

Pin Configurable or Selectable Oscillators, such as the 552AJ000366DGR, are a versatile and reliable choice for many different applications. This type of oscillator provides wide-ranging frequencies in a precise and stable output frequency. Its programmability also allows for a variety of different frequencies to be quickly and easily selected. This makes it an ideal choice for many different communication and frequency-synthesis applications.
