Oscillators

The application field and working principle of SIT1602AI-22-33E-18.432000D (hereafter referred to as SIT) in oscillator systems are similar to that of other quartz oscillators. Oscillators are electronic components that convert the internal direction current of the oscillator, phase, and frequency into an output signal pulse with a certain frequency. The voltage output from the oscillator is mainly used in the control, timing, frequency synthesis and other aspects of the microelectronic device.

SIT is a technical grade SMD VCXO, with ultra-small profiles and optimized performance levels for high frequency signal oscillation in the range of 16-22 GHz. The core working principle of SIT follows the traditional oscillator concept, where it uses a quartz crystal resonator to produce an accurate frequency output, while also employing a range of other electronic components to achieve its high-speed pulse generation and temperature stability.

The most important component in the SIT is a quartz resonator, which is created by carefully cutting a quartz crystal in a specific shape and size. It has the properties of low loss and high frequency stability, helping to ensure that the output frequency stays stable over a wide temperature range. The quartz resonator has a vibrational frequency in the range of 8 to 16 MHz and plays an important role in the oscillator circuit. The SIT makes use of a phase-locked loop (PLL) to maintain a constant frequency of oscillation. The PLL consists of an oscillator circuit, a divider, a phase comparator, and a voltage control device, which are used to lock the device onto a specific frequency.

Other than the quartz resonator, the oscillator circuit also contains a feedback capacitor, an inductor, a control voltage divider, and a voltage regulator. The inductor generates a high frequency oscillation signal and the feedback capacitor provides the necessary feedback for the oscillation to maintain the constant frequency. The offset and amplitude of the oscillation can be adjusted by the voltage control device, which receives the output from the phase comparator. The voltage regulator divides the input voltage to ensure that the signal is operated in the valid range and to reduce the effects of high linearity.

SIT is commonly used in electronic devices to generate high frequency signals to control the operation and timing. It is also used in measuring, frequency detecting, communications, navigation, and other applications. Due to its high accuracy and stability, SIT offers reliable and accurate operation with precise frequency control.

In conclusion, the application field and working principle of the SIT1602AI-22-33E-18.432000D in oscillator systems is similar to that of other quartz oscillators, relying on a quartz crystal resonator to produce an accurate frequency output and employing a range of other electronic components to achieve its high-speed pulse generation and excellent temperature stability. Its versatile applications have enabled it to be widely adopted in a variety of communication systems and microelectronic devices.
