Working Principle of SIT8009BCU71-33N

The SIT8009BCU71-33N is a standard voltage-controlled crystal oscillator (VCXO). A VCXO is an oscillator that uses a quartz crystal as its frequency-determining element. The frequency of the oscillator is controlled by an external voltage. As the voltage is increased or decreased, the frequency is linearly adjusted.

The SIT8009BCU71-33N consists of an input circuit, a voltage-controlled oscillator (VCO) circuit and a feedback circuit. The input circuit takes the input signal, amplifies it and passes it to the VCO circuit. The VCO circuit generates a reference frequency based on the input signal and the control voltage. The feedback circuit receives the reference frequency and compares it to the input signal. It then modifies the control voltage as needed to keep the reference frequency constant.

The SIT8009BCU71-33N also has a built-in circuit that suppresses jitter. Jitter is an unwanted frequency variation in the output signal. The jitter suppression circuit ensures that the output signal is free of unwanted frequency variations and is more stable than other oscillator types.

In summary, the SIT8009BCU71-33N is a voltage-controlled crystal oscillator that is ideal for many consumer electronic and special applications requiring precise frequency control. It has a wide frequency and voltage range, high stability and a jitter suppression circuit. Its versatile characteristics make it a suitable solution for many applications.
