Oscillators are broadly utilized in electrical gadgets and embedded systems, as they generate an electrical waveform with a predictable frequency and shape. The SIT8208AC-21-18S-33.60000Y is an example of an oscillator used for a multitude of applications – from timing clocks in PCs to providing phase-locked operation in radio circuits to defining the turn-on points in motor controllers. In this article, we will discuss the application fields and working principle of this oscillator.

SIT8208AC-21-18S-33.60000Y oscillators are commonly employed in microelectronics, computers, and communications devices, to name a few. The primary benefit of the oscillator is its feature of frequency stability, meaning that it can generate a steady frequency output over a wide temperature range. This frequency stability makes the SIT8208AC-21-18S-33.60000Y an ideal choice for applications such as precision timekeeping in watches, as well as accurate control of electromagnetic devices such as motors and actuators. The oscillators also allow for precise signal-processing steps in computer circuit boards, providing data rate control and clock pulses used to initiate communication with other devices.

The oscillator works by alternating current flows through two devices, such as a capacitor and resistor, forming a basic oscillating circuit. When the circuit is connected across a voltage source, the capacitor accumulates electric charge, until it reaches a certain voltage. As current flows from the voltage source through the components of the circuit, a sharp rise in voltage changes the current flow, until the capacitor becomes fully discharged and must be recharged. This oscillating process happens repeatedly, producing a square wave output.

The SIT8208AC-21-18S-33.60000Y oscillator further varies this basic model of an oscillating circuit through the use of a voltage-controlled oscillator or VCO. This VCO serves as the main oscillator, producing an output waveform with a frequency that is proportional to the input voltage. The frequency of the output waveform can be adjusted by altering the voltage applied to the VCO. By controlling the VCO with different voltages, the frequency range of the oscillator can be increased, and specific frequencies can be selected. Besides providing frequency variation, the VCO also works to adjust the oscillator’s output amplitude. As such, the SIT8208AC-21-18S-33.60000Y is able to produce stable oscillations with excellent frequency accuracy at very low distortion levels.

Notably, this particular oscillator has an operating frequency of 33.60000 kHz, a supply voltage of 21.0 V and a maximum supply current of 18 mA. Its frequency stability is guaranteed from -15°C to +85°C, and despite operating within this wide temperature range, its operating frequency drift is a maximum of only 30.0 ppm (parts per million). This frequency accuracy and drift ensure that the oscillator can precisely generate the desired frequency and keep it stable over time.

In summary, the SIT8208AC-21-18S-33.60000Y oscillator combines the properties of a traditional oscillator circuit with a VCO, resulting in a highly stable output frequency that can be used in a variety of applications. The wide temperature range, as well as the frequency accuracy and drift, make this oscillator particularly well-suited for applications in watches, motor controllers, communication systems, computers, and other electronics systems.
