Working Principle

The SIT1602BC-13-28E-12.000000E is a quartz Crystal oscillator. Quartz crystal can oscillate with precision in the MHz frequency range based on the piezoelectric effect. This effect occurs when an electric field applied to a quartz crystal causes the crystal to vibrate mechanically at its own natural frequency, which produces an electrical signal.

Quartz crystals are made of quartz, which is a piezoelectric material with electromechanical properties. When a voltage is applied to the crystal, it undergoes mechanical deformation, which then produces an electrical charge in proportion to the applied voltage. When the voltage is removed, the crystal returns to its original shape and generates a return electrical charge. This vibration of the crystal within the crystal oscillator produces a sine wave that is amplified and then used as a clock signal for electronic circuitry.

This oscillator also employs a feedback mechanism to ensure frequency stability over changing temperature and voltage. The oscillator circuitry consists of an amplifier that converts electrical energy into mechanical vibration, and a resonant element such as a quartz crystal to provide a stable frequency. The output of the amplifier is connected to the input of the crystal and when the frequency changes, the feedback will cause the amplifier to adjust its gain to maintain the original frequency. This ensures that the frequency remains stable over varying temperatures and voltages.

SIT1602BC-13-28E-12.000000E quartz oscillator is a reliable and low cost oscillator, providing reliable frequency stability for many applications. Its application fields are wide, and its frequency range is wide, making it one of the most popular oscillators in the market today.
