Oscillators

Oscillators are widely used in various electronic devices, such as radios, televisions, telephones, medical devices, and many other areas. They provide a means to generate a stable signal, usually for the purpose of timing, modulation and control. One of the most popular oscillators for such application is SIT1602BI-21-30N-18.432000E.SIT1602BI-21-30N-18.432000E is an oscillator with high precision and low power consumption. Its frequency range is from 16MHz to 31.999MHz, with the accuracy of ±20PPM or better and temperature coefficient down to ±15PPM or better. It provides two types of packaging and can be operated up to the temperature range of -40℉ to +85℃. It is designed to meet the highest requirements of electronic devices for timing clock signals for various application such as car audio systems, computer systems, audio/video equipment, DVD players, satellite receivers and many others. The main job of the oscillator is frequency determination and stabilization. Its oscillation frequency is determined by two key factors. The first one is the resonance of the inductor and capacitor in the tank circuit. The inductance of the tank circuit inductor and the capacitance of the capacitor together forms a tuned circuit, which sets the resonant frequency of the oscillator. The other factor is the external adjustment of the oscillator’s frequency. This adjustment could be accomplished by changing the values of capacitors on the tank circuit. The working principle of oscillators is based on LC or RC oscillation. The LC oscillations are produced when a capacitor connected to an inductor exchanges energy back and forth. This is a feedback mechanism and it behaves like an oscillator. As the charge stored on the capacitor increases, the voltage rises and the inductor opposes the current. This creates a back EMF and the capacitor starts to discharge to the inductor. This process continues until the capacitor is fully discharged, and then the cycle starts again. In addition, RC oscillators work on the same principle, but the components are different. An RC oscillator is composed of two resistors and a capacitor. It works when the capacitor charges up through one resistor and discharges through the other. This creates an oscillating current that will keep on going until the capacitor is fully discharged. Overall, SIT1602BI-21-30N-18.432000E is a great solution for those applications that require ultra-stable and reliable frequency oscillations. It can be used in various applications such as car audio systems, medical devices, timing control, radios, etc. It is also very efficient in terms of power consumption and temperature coefficient.
