Oscillators

Oscillators have been around since the 19th century and are essential components in many environments, ranging from audio and radio production to signal processing, medical instruments, and other industrial systems. Oscillators are used to generate or measure a signal sinusoidal (sine wave) or other related waveforms. The SIT8208AC-G2-28E-75.000000Y is an example of an oscillator used in a wide range of applications, and in this article, the topics of its application field and working principle will be discussed.

Application Field

The SIT8208AC-G2-28E-75.000000Y oscillator is designed for applications requiring very low noise levels, high stability, and long-term reliability. It is ideal for industrial control, medical instruments, telecommunications, and other general applications that require a precision frequency source. The oscillator is designed for signals from 10 kHz to 5 MHz, and can be operated at a temperature range of -40°C to +105°C, allowing it to be used in many different environments and applications. Another advantage of the oscillator is its low power consumption, which makes it well-suited for battery-powered applications.

Working Principle

The SIT8208AC-G2-28E-75.000000Y oscillator works on the principle of Resonant Circuit Technology (RCT). This is a proven technique that ensures a low phase noise, high output stability, and low power consumption in precision oscillators. The oscillator features a crystal resonator that is connected to two inverting amplifiers, which are in turn connected to a voltage-controlled oscillator (VCO). The crystal acts as a filter, rejecting undesired noise and harmonics while allowing only the precise frequency to pass through. The two amplifiers are used to provide a gain that amplifies the output signal, while the VCO is used to adjust the frequency of the signal.In addition to this, the SIT8208AC-G2-28E-75.000000Y oscillator has several advanced features that make it particularly well-suited for precision applications. These features include low jitter and spurious noise levels (better than -130dBc/Hz @ 10MHz), excellent phase stability, and a low frequency drift of less than 0.00001%.

Conclusion

The SIT8208AC-G2-28E-75.000000Y oscillator is a precision frequency source that is well-suited for industrial control, medical instruments, telecommunications, and other general applications. It works on the principle of Resonant Circuit Technology (RCT), which ensures a low phase noise, high output stability, and low power consumption. The oscillator has a frequency range of 10 kHz to 5 MHz and can operate in extreme temperatures, as well as offering low jitter and spurious noise levels, excellent phase stability, and a low frequency drift. As such, it is an ideal choice for many precision applications.
