Oscillators are widely used in the field of electronics and its applications can be quite varied. In particular, SIT8008BC-71-33E-12.288000G oscillator is a digital oscillator used in a number of applications. In this article, we will be discussing its application fields and the working principle behind it.

Application Field

SIT8008BC-71-33E-12.288000G oscillator is typically used in cellular phones, GPS systems, portable digital devices, and many other applications where frequency control and precise timing is required. It features low supply current consumption, fast start-up time, low jitter, and good temperature stability. This makes it an ideal choice for frequency control applications where space is a constraint.

Working Principle

The oscillatory behavior of this digital oscillator can be accomplished by using the CMOS logic gates. This oscillator consists of three logic gates arranged in a specific pattern. The three logic gates are exclusive-OR (XOR) gate, NAND gate, and inverter. By connecting the outputs of these three logic gates in a loop, an oscillatory behavior is created. The output of one of the gates is fed back to the input of another gate, and in this way, the oscillator circuit is formed. The oscillator also contains a capacitor which is used for damping the oscillations. The capacitor values can be adjusted to achieve a particular frequency.

SIT8008BC-71-33E-12.288000G oscillator achieves precise frequency control by making use of a temperature-compensated Crystal Oscillator (TCXO). A TCXO is a type of oscillator with an integrated thermistor that detects any changes in ambient temperature and corrects the oscillator frequency accordingly. This eliminates any frequency drift that may occur due to environmental temperature variations.

SIT8008BC-71-33E-12.288000G oscillator also features phase-locked loop (PLL) circuitry for further precision. PLL is used to lock the output frequency of the oscillator to a reference frequency. The reference frequency is created by an external feedback loop and is used to create an electrical phase that can be used to synchronize the oscillations.

Conclusion

In conclusion, SIT8008BC-71-33E-12.288000G oscillator is a digital oscillator that is used for precise frequency control in a variety of applications. Its low supply current consumption, fast start-up time, low jitter, and good temperature stability make it an ideal choice for frequency control applications in space-constrained scenarios. Furthermore, its use of a TCXO ensures that the oscillator frequency is not adversely affected by temperature variations and its PLL circuitry allows for further precise frequency control.
