Oscillators

Oscillators are devices that oscillate continuously between two different states. They are used in a variety of applications that require an external force to maintain an oscillatory motion. One of the most common types of oscillators is the SIT1602BC-32-25E-28.636300Y, a piezoelectric quartz oscillator.

Application Field

SIT1602BC-32-25E-28.636300Y oscillators are designed for a range of applications, including timing, frequency control, and frequency-locking. For timing applications, the devices are used to maintain precise synchronization between moving parts in, for example, watches and clocks. In frequency control, the oscillators are used to adjust frequencies in accordance with requirements set by industry standards. And in frequency-locking, the oscillators are used to ensure a device is running at a constant frequency when it is connected to an external frequency reference.

Working Principle

The working principle of SIT-1602BC oscillators is based on the piezoelectric effect. Piezoelectricity is an electric charge that is produced when a mechanical stress is applied to certain materials. These materials are known as piezoelectric materials. This electric charge is then used to create an oscillatory motion in the material, which is then used to Time, Control, and Lock frequencies.

The oscillators use a small crystal of quartz in combination with a conductive metal plate printed ceramic substrate. When a voltage is applied across the plates, it causes mechanical stress on the quartz crystal, resulting in oscillations that can be precisely controlled. This is known as quenching circuitry. In addition to this, the substrate is designed to isolate the sensitive quartz crystal from significant fluctuations in voltage and temperature.

To precisely control the oscillations of the quartz crystal, the oscillator employs a feedback mechanism known as the Pierce Oscillator configuration. This feedback mechanism involves two tuned circuits that are connected to the quartz crystal. The first tuned circuit, known as the pre-amplifier, increases the amplitude of the crystal\'s oscillations. The second tuned circuit, known as the amplifier, amplifies the oscillations and sends them back to the crystal. The feedback loop is designed to ensure the oscillations remain at the desired frequency, making SIT1602BC-32-25E-28.636300Y oscillators highly precise.

Conclusion

The SIT1602BC-32-25E-28.636300Y oscillator is an example of a device that employs the piezoelectric effect in order to produce a range of oscillatory motion. The device is designed to be used in timing, frequency control, and frequency-locking applications where accuracy and precision are of the utmost importance. It does so by utilizing the Pierce Oscillator configuration and quenching circuitry, resulting in a highly precise and reliable oscillator.
