Introduction of SIT8209AC-G2-25S-133.000000T Oscillator

SIT8209AC-G2-25S-133.000000T Oscillator (also known as VCXO or Voltage Controlled Crystal Oscillator) is a special type of oscillator used to generate a stable and precise frequency via frequency control from the voltage applied to the oscillator. It is a product from the series of SIT Oscillators (Series Isolated Technology Oscillators) that was designed and engineered by SiTime Corporation, an American company that specializes in the manufacturing a wide variety of timing solutions from Silicon MEMS technology.

Application Field of SIT8209AC-G2-25S-133.000000T Oscillator

The SIT8209AC-G2-25S-133.000000T Oscillator is designed for use in applications that require a lightweight, precise, and low-cost solution. It can be used in systems that need a low voltage oscillator to generate stable frequency, such as USB Prototyping Boards, Networking Devices, Wireless Communications, Mobile Phones, and Data Communications.

Working Principle of SIT8209AC-G2-25S-133.000000T Oscillator

The SIT8209AC-G2-25S-133.000000T Oscillator uses a combination of a crystal and a voltage variable resistor to adjust the oscillator’s frequency. The crystal is selected to oscillate at a specific frequency when the voltage applied to it is at a specific value. The frequency of oscillation can then be changed by varying the voltage applied to the crystal.The crystal is connected to two electrodes (A and B) and each electrode is connected to two different resistors. These resistors form a voltage variable resistor whose output is connected to the crystal electrode. The voltage variable resistor can be adjusted by varying the voltage applied to it. This varying voltage changes the resistance of the resistor and hence the frequency of oscillation of the crystal.The SIT8209AC-G2-25S-133.000000T Oscillator also has a temperature compensated circuit which keeps the frequency of oscillation stable, even when the temperature and the supply voltage of the oscillator change. This makes the oscillator suitable for use in temperature sensitive systems.

Conclusion

The SIT8209AC-G2-25S-133.000000T Oscillator is a versatile and reliable solution for applications where a stable and precise frequency is required. It is designed to be lightweight, low-cost, and temperature compensated to maintain accuracy and stability in different environmental conditions. It is well suited for applications such as USB Prototypes, Networking Devices, Wireless Communications, Mobile Phones, and Data Communications.
