Pin Configurable/Selectable Oscillators are popular devices used in many applications. The 552BE000121DGR is one of these oscillators, and understanding its application field and working principle is essential for utilizing it effectively.

Application Field

The 552BE000121DGR is an integral type oscillator with pin selectable frequency. It is constructed from a quartz crystal, a quartz resonator and its equivalent circuit, a bridge diode and capacitive elements, making it a very reliable electronic device. It is suitable for use in electronic instruments, communication receivers and test equipment, as well as for frequency control of mechanical systems such as motors, actuators and servomechanisms.

This model offers exceptional performance, including a volatage-controlled frequency range from 375 kHz to 16.000 kHz, with an accuracy of +/-1 kHz. Its impressive low-power consumption, high stability and small size make it ideal for many different applications. Furthermore, it has the ability to maintain frequency and temperature due to its high quality quartz oscillators.

The 552BE000121DGR can also be used in voltage controlled oscillator (VCO) applications, as the device uses a low-power and low-voltage oscillation circuit that is easy to control.

Working Principle

The 552BE000121DGR uses a quartz crystal to generate a predictable frequency. A quartz crystal functions as a piezoelectric element that, when subjected to an external electric field, produces an electric charge on two sharp edges, resulting in an oscillation frequency with a generator circuit. When an external voltage is applied to the quartz crystal, the frequency of the oscillation changes.

The 552BE000121DGR works by accepting an input voltage, which is then multiplied by a specific value so as to produce the required frequency. This is done through an oscillator circuit system, which includes a quartz resonator, two bridge diodes and two capacitive elements. The two capacitive elements are connected directly to the oscillator and generate an alternating voltage, while the two bridge diodes are used to control the current. The oscillator circuit then adjusts the frequency of the output according to the input voltage.

Conclusion

The 552BE000121DGR is a highly accurate, low-power pin selectable oscillator, with a wide application field. It is suitable for use in many different applications, due to its stability, low-power consumption and small size. Its excellent performance makes it an ideal choice for VCOs and frequency control of mechanical systems. The oscillator also works on the principle of a quartz crystal, which when subjected to an external electric field produces an electric charge on two sharp edges, resulting in an oscillation frequency with a generator circuit.
