Oscillators

An oscillator is an electronic circuit or device used to generate a periodic, or oscillating electronic signal. Oscillators convert direct current (DC) from a power supply to an alternating current (AC) signal. As their name implies, they produce results (i.e. voltage fluctuations) at a frequency determined by the circuit design. The specific type of oscillator discussed here is the SIT8209AC-G2-25E-106.250000T, a temperature compensated crystal oscillator (TCXO).

Application field

The SIT8209AC-G2-25E-106.250000T is used in a variety of applications. It is often found in cell phone, tablet, and laptop computers. It is also used in medical, automotive, and defense applications often requiring a high level of accuracy. GSM, CDMA, 4G and LTE technologies are just a few of the applications where the TCXO can be utilized. The TCXO is also used to generate radio frequency (RF) signals in commercial and military applications. It is used to generate frequencies that range from shortwave radio and FM to GSM and Wi-Fi networks. In aerospace applications where timing is of the utmost importance, the TCXO is the go to oscillator.

Working principle

The SIT8209AC-G2-25E-106.250000T TCXO operates using a quartz crystal and an amplifier. Quartz crystals contain two electrodes – one that is positively charged and the other that is negatively charged. When an electric charge is applied to the electrodes, a voltage develops across them which creates an electrical field capable of compressing the quartz crystal, resulting in the production of a known frequency of soundwaves.The amplifier is used to amplify the signal generated by the crystal and can be adjusted to match the desired frequency. The amplifier can also be used to filter frequencies and reduce noise in the signal.The TCXO is highly accurate, stable, and reliable due to the quartz crystal. It is capable of maintaining its accuracy in a wide variety of temperatures and environments. This makes it especially attractive for applications requiring accurate and consistent signals in unpredictable conditions.

Conclusion

The SIT8209AC-G2-25E-106.250000T TCXO is a type of oscillator that is used in various applications where accuracy and reliability are of the utmost importance. It operates through the use of a quartz crystal and amplifier to generate a known frequency. It is highly accurate, stable, and reliable which makes it a go to oscillator for many industries.
