Oscillators: SIT1602BC-23-30S-28.636300D Application Field and Working Principle

Oscillators are electronic circuits that generate repeating waveforms in the form of an electrical signal from a given input. They are essential components in many applications in the field of electronic engineering. The SIT1602BC-23-30S-28.636300D is a popular model oscillator, which is compact and typically used in frequency-controlled systems. This article will explore this oscillator’s application field and working principle.

Application Field

The SIT1602BC-23-30S-28.636300D oscillator is primarily used for frequency control in microprocessors, with frequency control range up to 28.636 MHz. These oscillators use a crystal (piezoelectric) resonator to provide high accuracy and high stability, making them ideal for microprocessor-controlled systems. Furthermore, the oscillators are capable of operating over a wide temperature range without the need for additional components, such as thermistors or temperature-compensating crystals. This makes them suitable for use in applications that require stable operation over a wide temperature range, such as consumer and automotive electronics. The SIT1602BC-23-30S-28.636300D oscillator is also used in frequency-dependent control systems, such as in radio transmitters and receivers. Due to its frequency accuracy, it is used in broadcasting to control the frequency and ensure that signals remain consistent. Furthermore, it can be used in digital communication systems, such as cellular networks and wireless LANs. The oscillator can provide precise frequency control in such systems, helping to maintain clear communication between two points and prevent interference from other devices. Finally, the SIT1602BC-23-30S-28.636300D oscillator can be used in power supplies to regulate voltage output. The oscillator helps to ensure that the output voltage remains steady, even when the input voltage fluctuates. This helps to protect sensitive electronic devices from damage due to voltage overloads or low voltage conditions.

Working Principle

The SIT1602BC-23-30S-28.636300D oscillator works on the principle of a crystal oscillator circuit. The circuit consists of a quartz crystal placed between two electrodes, with the resonance frequency of the crystal determined by the size of the quartz and the capacitance of the electrodes. The frequency of the oscillator is determined by the resonant frequency of the quartz crystal.When a voltage is applied to the electrodes, they become electrically charged, causing the quartz crystal to vibrate at its resonant frequency. This vibration produces a current which is amplified and sent to the output of the oscillator. The current amplitude is determined by the frequency, as a higher frequency will result in a higher current amplitude. The SIT1602BC-23-30S-28.636300D oscillator also makes use of a phase-locked loop (PLL) circuit, which is a type of closed-loop feedback mechanism used to maintain a stable output frequency. The PLL circuit consists of a reference oscillator, a frequency divider, a phase detector, a low-pass filter and a voltage-controlled oscillator (VCO). The output frequency is determined by the frequency of the reference oscillator and the ratio between the frequency divider and the VCO.When the oscillator’s output frequency begins to drift, the phase detector compares the reference oscillator’s frequency with the divided-down frequency from the VCO. If there is a difference, it sends a signal to the low-pass filter, which in turn adjusts the voltage supplied to the VCO, adjusting its frequency and returning the output of the oscillator to its desired value.

Conclusion

The SIT1602BC-23-30S-28.636300D oscillator is a popular choice for frequency control in microprocessors and many other applications due to its accuracy, stability and wide temperature range. It works on the principle of a quartz crystal oscillator circuit and employs a phase-locked loop control circuit to ensure a stable output frequency. It is an essential component in many electronic engineering applications and helps to ensure reliable performance in frequency-dependent control systems.
