<p>Oscillators are electrical and electronic components used to generate electrical signals with a specific frequency. SIT1602BI-12-30N-66.666660D oscillators are specialized oscillators which are used in diverse range of applications, and are specifically designed to generate precise signal frequencies with high accuracy. <p>The SIT1602BI-12-30N-66.666660D is primarily used in paging, wireless data transmission, radio frequency identification (RFID), medical monitoring, and communication systems. As the frequency accuracy is critical in these applications, it is necessary to select highly accurate oscillator products for these types of applications.The SIT1602BI-12-30N-66.666660D oscillator has excellent short term stability, temperature stability, frequency aging rate and cycle-to-cycle jitter making it suitable for critical frequency applications.<p>The SIT1602BI-12-30N-66.666660D oscillator’s working principle is based on the dynamical system consisting of a resistive-capacitive (RC) network and the oscillation frequency is determined by the resonance frequency of the resistor-capacitor pair. The RC network comprises a resistor and a capacitor connected in series and these components form a voltage divider circuit. The output voltage is the “ringing” voltage of the capacitor. When a voltage is applied to the input of the oscillator (at pin 12), it activates the RC network by charging the capacitor. The capacitor discharges periodically and the output voltage increases exponentially. This voltage peaks, decreases, and then appears at the output terminals (pins16,17) with a 180-degree phase shift. <p>The SIT1602BI-12-30N-66.666660D oscillator is made up of a number of components, such as an amplifier, JFET transistors, resistors, capacitors, output terminals, and an oscillator circuit. The oscillator circuit is the core of the oscillator, it is capable of generating a stable, accurate and repeatable oscillation frequency when connected to a voltage source. The amplifier boosts the input signal and amplifies the signal that is fed into the JFET transistors. The JFET transistors provide the gain, and they regulate the waveforms of the output signal. The resistors and capacitors are used to filter out all noise from the input signal. Finally, the output terminals provide an output signal that is frequency- and phase-stable. <p>The SIT1602BI-12-30N-66.666660D oscillator provides a reliable, accurate, and repeatable frequency that can be used in critical applications where precise frequency stability is needed. It is capable of supporting wide range of frequencies, and it has a very fast switching speed to achieve its applications. The small size, low power consumption and high frequency accuracy also make the SIT1602BI-12-30N-66.666660D oscillator a desirable device for many applications. </p>
