Oscillators are divided into different types. SIT8209AC-G1-25S-166.666660X belongs to the group of frequency synthesizers, which has been widely used in a variety of application fields for many years. This article will explain the application field of this frequency synthesizer and its working principle.

Application Field

The SIT8209AC-G1-25S-166.666660X frequency synthesizer is mainly used in modern telecommunication systems such as distance digital equipment, such as wireless communication systems, digital broadband receivers, satellites and other communication systems. In these applications, the frequency synthesizer provides a convenient and efficient way to generate accurate and stable frequencies from a low reference frequency.

In addition, this frequency synthesizer can also be widely used in industrial applications where accurate and stable frequency is required, such as frequency control feedback devices for control systems of equipment, small-powered motors and pumps, precision timing applications such as timing systems for industrial control systems, as well as timing for other special components.

Working Principle

The SIT8209AC-G1-25S-166.666660X frequency synthesizer works by using a phase-locked loop (PLL) technique to produce a precise frequency output from a given low reference frequency. The phase-locked loop is a circuit composed of a voltage-controlled oscillator (VCO), a frequency divider/comparator, and a low pass filter. The VCO is designed to generate an output frequency that is proportional to its control voltage, which is the reference frequency input to the frequency synthesizer.

The frequency output from the VCO is divided using the frequency divider, and the output of the divider is compared to the reference frequency. The resulting error signal is then passed through a low-pass filter. The error signal is then fed back to the VCO, which causes its output frequency to be controlled to match to the reference frequency. The result is an accurate and stable output frequency.

The SIT8209AC-G1-25S-166.666660X frequency synthesizer is designed to work with a low reference frequency of 2.0 MHz, and its output frequency can be varied by using a programmable clock source. By adjusting the control voltage of the VCO, the output frequency can be set from 166.6666 MHz to 166.6666 MHz +/- 10%.

The SIT8209AC-G1-25S-166.666660X frequency synthesizer is a highly reliable and versatile device, which can be used for a wide range of applications where accurate and stable frequency is required.
