353VB6A400R Working Principles

The 353VB6A400R oscillator operates on a standard Crystal Oscillator circuit. The basic circuit consists of a crystal, two capacitors, an amplifier and a resistor, as illustrated in the figure below.

The circuit works as follows: when the power is turned on, the two capacitors C1 and C2 are charged. This creates an electrical difference between the base and collector of the transistor, causing the current to flow by the transistor. As the current flows through the circuit, the voltage will oscillate between the base and the collector of the transistor, generating a sine wave.

The frequency of the sine wave is determined by the characteristics of the crystal. This frequency can be adjusted by changing the value of capacitors C1 and C2, allowing the user to set the output frequency of the oscillator to the required value.

The 353VB6A400R oscillator also features a temperature compensation circuit, which ensures that the temperature of the oscillator remains stable and does not drift, providing reliable frequency stability over wide temperature range.
