Pin Configurable/Selectable Oscillators are oscillators that are designed with a digital interface which allow user to configure the oscillator frequency, stability, and amplitude without the need for any special signals. Commonly referred to as 555 Oscillators, these oscillators are popular for their versatility, low cost, and easy to use interface. The use of these oscillators is especially advantageous in environments that require quick and easy frequency switching, low noise, and accuracy and stability. Common applications for these oscillators include wireless communication, audio systems, digital counter indicators, and motor speed control.

The 555BC000209DG is an example of such a pin selectable/configurable oscillator. This oscillator is designed to operate with a 14-pin configuration. Designed with a maximum operating temperature of 150 degrees Celsius and a maximum frequency of 1MHz, it is well suited to many of the applications mentioned above. By varying the frequency with the on-board digital pot, this oscillator provides an accurate, stable frequency that is consistently adjustable even in the event of extreme environmental changes.

Using CMOS technology, the 555BC000209DG has a very low power consumption, and creates very few EMI emissions. This makes it a great choice for applications in which noise is a concern. The 1.8 to 5.5 V power supply voltage range also makes it a great choice for use in battery powered applications as it provides a very suitable power budget.

The 555BC000209DG also offers an exceptional level of stability and accuracy. With a total accuracy rate of 0.2ppm and an initial tolerance rate of 0.5ppm, the oscillator guarantees precise frequency settings and a high degree of accuracy throughout the operating temperature range. This ensures the oscillator will remain precise and consistent throughout the entirety of its operation.

The 555BC000209DG oscillator works by utilizing a phase-locked loop (PLL) circuitry. This circuitry utilizes a phase comparator to compare the input frequency with a voltage controlled oscillator (VCO). The phase comparator then compares this voltage with a reference voltage to determine the phase difference between the two. This phase difference is then adjusted until they are the same, which produces a very stable and accurate frequency output.

To maximize the utility of the 555BC000209DG oscillator, the user can configure the frequency settings through the on-board interface panel. This feature allows the user to easily adjust the oscillator settings without the need for external switch connections or expensive connections such as a PC. This also eliminates the need for constant manual frequency changes and provides a simple and efficient way to make frequency adjustments.

Overall, the 555BC000209DG pin selectable/configurable oscillator provides an excellent solution for users who need a reliable and versatile oscillator capable of a wide range of frequency settings. With its high accuracy rate, low power consumption, and ability to be configured through a pin interface, the 555BC000209DG is an ideal choice for many applications, including wireless communication, audio systems, digital counter indicators, and motor speed control.
