Oscillators are essential devices used in most electronic circuits. Such components are used to generate electrical signals at a defined frequency and usually include some form of feedback mechanism in order to ensure that the signals generated remain stable. The SIT9120AC-1C2-25E125.000000T oscillator is one such device and has specific applications and a working principle that deserve to be understood better.

Applications

The SIT9120AC-1C2-25E125.000000T oscillator is primarily designed for timing applications in radio-frequency (RF) circuits. The device comes with an output frequency of 433.92 MHz and a wide range of output levels; from 4dBm to 8dBm. This means that the device can be used in a wide variety of radio systems, including Bluetooth Low Energy, digital audio broadcast (DAB) systems, wireless local area networks (WLANs), Zigbee, microwave ovens, and wireless keyboards.

The device also has the ability to operate over a wide temperature range, from -40°C to +105°C. This makes it suitable for outdoor applications or in areas where temperature is likely to fluctuate significantly. Additionally, it has a fast settling time of less than 30ms, making it an ideal choice for high-speed systems.

Working Principle

The SIT9120AC-1C2-25E125.000000T oscillator operates on a phase shift principle. To do this, the device uses an inverting amplifier. This amplifier is used to sample the output signal and measure the phase shift between the input signal and the output signal. This phase shift is then used to adjust the oscillator frequency so that it is always in-sync with the input signal.

The oscillator also uses a voltage-controlled oscillator (VCO) to generate the output signal. This VCO is adjustable over a wide range of frequencies, allowing for a wide variety of output signals. The output signal is then amplified by the inverting amplifier and its phase is compared to the incoming signal.

In order to ensure that the output signal stays in-sync, the oscillator also makes use of a feedback mechanism. This mechanism is used to adjust the VCO, so that any difference in the phase shift is corrected, and the output signal stays in-sync. By doing this, the oscillator can maintain the output frequency even when the input frequency is changing.

In summary, the SIT9120AC-1C2-25E125.000000T oscillator is a useful device for timing applications in RF circuits. It uses an inverting amplifier and a VCO in order to generate a stable output signal. This signal is then compared to the incoming signal, and the feedback mechanism is used to ensure that the output frequency remains the same even when the input frequency is changing.
