Pin Configurable/Selectable Oscillators: 554BF000159DG Application Field and Working PrincipleOscillators are electronic devices used to control the frequency and time interval of electronic signals. Pin Configurable/Selectable Oscillators are special oscillators that allow the user to adjust their frequency and time interval via external pins. The 554BF000159DG Pin Configurable/Selectable Oscillator is one such device that offers high performance, wide range and cost-effective performance. Due to its unique properties, it can be used in a variety of fields including telecommunications, automotive, medical, and military. This oscillator is constructed using a quartz crystal resonator, or a combination of both quartz and ceramic resonators. The combination of these materials helps increase the stability and accuracy of the oscillator under different conditions. In addition, the 554BF000159DG oscillator features a PLL (Phase Locked Loop) resonator stability and a frequency range of 0.4 MHz to 680 MHz. The working principle of this oscillator is relatively simple. When an external voltage source is applied, an electrical AC signal is generated which is written onto a capacitance-filled quartz resonator. This causes the quartz crystal to vibrate and oscillate at a certain set frequency determined by the capacitance, producing an output signal on the oscillator’s pins. The frequency and time interval of the oscillator can be adjusted by adjusting the external voltage source.To select the desired frequency, the 554BF000159DG oscillator has two input pins that can be used to adjust the frequency. These pins act as voltage dividers, allowing the user to determine which frequency they want the oscillator to oscillate at. The oscillator also has a selection pin that when connected to a specified voltage, allows the user to select from a range of preset frequency modes. The 554BF000159DG oscillator provides excellent accuracy and stability, making it extremely suitable for high-performance applications. It features high stability and accuracy with ±20 ppm of stability at 25°C, ±50ppm of stability at 40°C, and ±60 ppm of stability at 70°C. In addition to its stability, the oscillator also has a low power consumption of 8 mA, allowing it to be used in battery-powered applications.Lastly, the 554BF000159DG oscillator is housed in a small form factor of 5.5 mm x 4.0 mm, allowing it to be easily integrated into existing designs. The oscillator is also lightweight and compact, making it perfect for portable applications. Overall, the 554BF000159DG Pin Configurable/Selectable Oscillator is an ideal device for applications that require a high degree of accuracy, performance and stability. This oscillator can easily be adjusted to a wide range of frequencies, making it an excellent choice for applications in various fields including telecommunications, automotive, medical and military.
