TTETTLJANF-20.000000 Application Field and Working Principle

The TTETTLJANF-20.000000 is an oscillator designed to provide a stable, repeatable oscillation frequency with an accuracy of up to ± 0.2%. It is mainly used in high-precision electronic weighing and counterbalance scales, and other applications requiring precise frequency control.

The oscillator consists of several components, including its main timing element, a quartz crystal. The quartz crystal is a type of piezoelectric material capable of vibrating at a specific frequency when a specific voltage is applied to it. This vibration is converted into an electrical signal of a specific frequency. This output frequency can be adjusted by changing the voltage applied to the quartz crystal.

This oscillator also uses two amplifying transistors to provide a higher gain signal from the quartz crystal. The transistors also act as a feedback mechanism, providing a consistent frequency output. The output frequency is further modified by using a variable resistor to fine-tune the frequency.

The oscillator is then connected to a precision reference, typically a temperature-compensated voltage-controlled oscillator, or VCO, and an amplifier. The VCO provides a very accurate reference source, while the amplifier ensures that a consistent oscillation frequency is maintained.

The TTETTLJANF-20.000000 oscillator provides a low-drift oscillation frequency, allowing it to be used in high-precision applications. Furthermore, the oscillator has a wide temperature range and excellent EMC immunity, allowing it to remain stable under environmental changes.

In summary, the TTETTLJANF-20.000000 is a stable, repeatable oscillator, designed to provide a precise and consistent frequency output that can be used in a variety of high-precision applications. It features a wide temperature range, excellent EMC immunity, and a frequency accuracy of up to ± 0.2%.
