Oscillators
Oscillators are electronic components used to generate oscillations, or repetitive signals, at certain frequencies. To achieve a stable oscillation, the inductor and the capacitor have to be in an oscillation loop storage device. Oscillators provide a stable reference frequency signal used for radio frequency, industrial automation, and communication systems. They are often permanent or semi-permanent parts of a device, though they may also be reprogrammed in certain cases. An example of an oscillator is the SIT8209AC-8F-28E-166.000000Y.
Application Field and Working Principle of SIT8209AC-8F-28E-166.000000Y
The SIT8209AC-8F-28E-166.000000Y is a low-frequency quartz crystal oscillator. It is a high precision device that can be used in a variety of industrial and communication applications such as base station testers, analog-to-digital (ADC), pulse oximetry, clock generation, radar and telecommunications applications. The compact design also makes it suitable for embedded systems.
The SIT8209AC-8F-28E-166.000000Y is based on a mechanical resonance principle using an LC resonator. The oscillator consists of a quartz substrate, a metal package, and a miniaturized, compact design. The substrate is made of piezoelectric material such as quartz, which is polarized in a specific direction. The metal case is typically hermetically sealed to prevent contamination from external environmental conditions. When an alternating voltage is applied to the substrate, a mechanical resonance is set up, causing the crystal to vibrate at its natural resonant frequency. The resulting oscillation generates a stable frequency reference signal, which the output amplifier then converts to electrical form and delivers as its output.
The frequency and temperature of the oscillation is closely linked. It follows that the oscillator must be able to operate across a wide temperature range. The SIT8209AC has a wide operating temperature range of -40°C to +95°C. This makes it suitable for use in harsh environmental conditions. In addition, it has low phase noise, low-power consumption, and a high stability over multiple temperature changes.
The SIT8209AC is designed to provide reliable oscillations over short and long periods of time. It has a Phase Noise performance of -130dBc/Hz at 100KHz which makes it suitable for applications that require high signal purity and a low level of noise. The device also has a wide supply voltage range of 2.97~3.63V, which makes it more energy efficient and reduces part cost.
Conclusion
The SIT8209AC-8F-28E-166.000000Y is an excellent choice for low-frequency applications due to its stability, wide operating temperature range, and low power consumption. The design allows it to be used in a wide variety of industrial and communication applications. Additionally, it offers a high level of signal purity and low level of noise.
