Working Principle

The SIT1602BC-21-18E-66.666000D oscillator works based on a crystal, a fixed-frequency circuit, and a voltage-controlled oscillator (VCO). Its basic operation consists of a fixed-frequency circuit, which is composed of a crystal, a load capacitor, and impedance matching circuits. The crystal vibrates at a constant frequency and needs to be highly accurate and stable. The impedance matching circuit matches the electrical impedance between the crystal and the load capacitor to ensure that the maximum energy can be transmitted.

The VCO is used to convert periodic input signals into periodic output signals. It converts the fixed frequency signal generated by the fixed-frequency circuit into an alternating signal through a certain amplitude modulation. This alternating signal is then fed back to the input of the fixed-frequency circuit to generate an oscillating signal. This oscillating signal is amplified by a buffer amplifier to generate a higher-power output oscillation signal. This signal is then used as the timing signal for the digital circuit.
