Oscillators are essential components in many electronic systems. They provide timing, frequency, amplitude and/or phase control to systems. One particular type of oscillator, the SIT 8208AI-81-28S-37.500, is a combination quartz crystal oscillator with resonator.

Application Field:

The oscillator is well-suited to a wide range of applications, particularly those that require precise timing or phase control. It has been successfully used in the telecommunications, automotive, medical, instrumentation, and aerospace industries. Common applications include digital filters, timing circuits, communication systems, motor controllers, navigation systems, surveillance systems, robotics, power supplies, broadcast equipment, and automatic test equipment.

Working Principle:

The oscillator operates by exploiting the properties of quartz crystals. Quartz is a piezoelectric material, meaning that it has the ability to convert electric signals into mechanical vibration, and vice versa. Quartz crystals can vibrate at very specific frequencies when correctly stimulated. By carefully tuning an electrical signal to one of these resonance frequencies, the quartz crystal can be made to vibrate at that frequency and thus produce an oscillating signal.

The SIT 8208AI-81-28S-37.500 oscillator uses a combination quartz crystal resonator and oscillator, and contains a parallel resonant quartz slab and a low capacitance ceramic base. The quartz slab is cut at specific angles so that it has two vibration modes when driven by alternating current. The frequency is adjusted via a variable capacitance applied to the quartz crystal.

The oscillator is buffered by an amplifier circuit which then serves the output signal. The output may take several different forms, depending on the application. It could be an extremely low distortion sine wave, or a sinusoidal waveform with multiple harmonics. High-frequency waveforms used in communications can also be generated.

Due to the wide range of applications in which the SIT 8208AI-81-28S-37.500 oscillator can be used, the oscillator is designed for maximum flexibility. It has an operating temperature range of -30°C to +85°C, and an output specified over an operating voltage range of 3.0V to 5.5V. Output synchronisation and buffering stages can be adjusted to suit the needs of the system.

Conclusion:

The SIT 8208AI-81-28S-37.500 crystal oscillator has a wide application field, and is suitable for a variety of industrial and commercial applications. Its stability and accuracy makes it an ideal choice for applications that require precision timing or phase control. The oscillator can be easily adjusted to provide a range of output signals, making it highly suitable for all sorts of systems.
