Oscillators are electrical circuits, which generate an output of regular and repetitive pulses of voltage at a specific frequency. The frequency of oscillation is determined by its components. The 638V156H3I3T oscillator is a temperature-compensated crystal oscillator (TCXO) widely used in precision frequency control. Operating over a wide temperature range, the oscillator can provide higher stability and accuracy than a standard crystal oscillator. In this article, we will discuss the application field and working principle of the 638V156H3I3T oscillator.

Application Field

The 638V156H3I3T oscillator is mainly used as a precision frequency control in precision timing applications. As it is temperature-compensated, the oscillator offers greater stability and accuracy than a standard crystal oscillator. Due to its wide operating temperature range, it is particularly suitable for use in environmental conditions with high temperatures and large temperature fluctuations. It provides excellent performance over the full temperature range and offers superior system performance, thus delivering reliable operation. The oscillator can also be used in a wide variety of other applications such as telecommunications, radio communication, navigation systems, and data processing.

Working Principle

The 638V156H3I3T oscillator is a type of temperature-compensated crystal oscillator (TCXO). The oscillator works by introducing a temperature compensation element to an oscillator circuit containing a crystal and frequency control circuit. The temperature compensation element balances the temperature-drived frequency variations of the circuit, thus providing a more stable output frequency over a wide temperature range. The oscillator is based on four basic elements: a crystal resonator, a temperature sensor, an operational amplifier, and a temperature compensation circuit. The crystal oscillator produces a periodic signal, which is used as the input to the temperature sensor. The temperature sensor senses the temperature and measures the frequency deviation from the desired frequency. The operational amplifier amplifies the signal from the temperature sensor and passes the amplified signal to the temperature compensation circuit. This circuit then implements the appropriate temperature compensation to ensure that the desired frequency is accurately maintained.

Conclusion

The 638V156H3I3T oscillator is a precision frequency control oscillator, widely used for its excellent performance over wide temperature ranges. It is mainly used for precision timing applications and can also be used in telecommunications, radio communication, navigation systems, and data processing. The oscillator works by introducing a temperature compensation element to an oscillator circuit containing a crystal and frequency control circuit, thus providing a more stable and accurate output frequency.
