Oscillators

Oscillators use frequency as a signal source of an electrical definition to generate a periodic signal, which typically consists of a sine wave, square wave, triangle wave, or another wave shape. As a core component of electronic devices, oscillators have a wide variety of applications. In this article, we will discuss the application field and working principle of the SIT8209AC-G3-28E-156.250000Y.

Application Field

Additionally, its ultra-low-profile package and ultra-compact enclosure makes it suitable for all types of minimalistic designs. Moreover, the product has a high shock and vibration resistance which makes it suitable for vibration and shock-prone environments. The oscillator also offers excellent jitter performance at low power consumption and high temperatures.

Working Principle

The working principle of the SIT8209AC-G3-28E-156.250000Y is based on the charging and discharging of a capacitor. An RC oscillator circuit works similarly to an LC oscillator circuit. In a RC oscillator, a resistor is connected in series with a capacitor which is connected in parallel with the inductor. When an AC current passes through the capacitor, it charges up and discharges, depending on the frequency of the signal. The frequency of the oscillation is determined by the time constant, TC = R*C, of the circuit. This time constant is equal to the product of the resistance (R) and the capacitance (C). By changing the value either of the two components, the oscillator frequency can be changed. The oscillator produces a sine wave signal with a specific frequency which is determined by the R and C components of the circuit. In summary, the SIT8209AC-G3-28E-156.250000Y is a miniaturized CMOS oscillator from Aktimic which is suitable for small electronic circuits and can operate in extreme temperature levels. The oscillator has a wide range of applications including consumer electronics, automotive control systems, medical equipment, toys & games, surveillance, color TVs, automotive audio systems, industrial control systems and communications systems. Additionally, its working principle is based on the charging and discharging of a capacitor and the frequency of oscillation is determined by the time constant, TC = R*C, of the circuit.
