Oscillators are electronic devices used to produce a periodic output signal of steady frequency. Common examples include crystals, resonators, inductors, and phase-locked loops (PLLs). The SIT8208AC-G1-33E-33.333330T is a type of oscillator. This article will discuss its application field and working principle.

Application Field

The SIT8208AC-G1-33E-33.333330T is a high frequency voltage controlled oscillator (VCO). It is designed for use in applications where frequency stability and tuning range are essential, such as WLAN, Bluetooth,, GSM, CDMA and other wireless communication systems. Its features include wide frequency range, wide tuning range, high reliability, and low power consumption. It is also suitable for applications that require accurate frequency control and high up-conversion or down-conversion capabilities.

Working Principle

The SIT8208AC-G1-33E-33.333330T works by using a voltage-controlled oscillator (VCO) and a phase-locked loop (PLL) circuit. The VCO is used to generate an oscillating signal of peak-to-peak voltage with a certain frequency. The PLL circuit then compares the output signal to a reference frequency. A frequency comparison between the two signals is then made, and the output signal is adjusted accordingly. This allows the oscillator to achieve high accuracy over a wide frequency range, and also offers frequency stability.

The SIT8208AC-G1-33E-33.333330T also uses a number of components to control the amplitude, center frequency, and fine tuning of the oscillator. In order to control the amplitude, the PLL circuit uses anautomatic gain control element. This mechanism adjusts the gain of the amplifier depending on the amplitude of the output signal. For center frequency control, a frequency divider is used to divide the PLL reference frequency by a certain factor. Finally, the fine tuning of the oscillator is achieved by a pair of series resistors which can be adjusted based on the voltages applied.

The SIT8208AC-G1-33E-33.333330T is a high performance oscillator that is highly suitable for wireless communication applications where frequency stability, tuning range, and accuracy are key requirements. Its PLL circuit and VCO combination offer a wide frequency range, high reliability, and low power consumption.
