Oscillators

Oscillators are devices that generate an alternating electrical signal with a certain frequency, typically a sine wave, square wave, or triangle wave. They are used in a variety of applications, including clock generation, timing, signal synthesis, and signal processing. The TC-12.200MCE-T is one type of oscillator, and it has a number of applications and working principles.

TC-12.200MCE-T Application Field

The TC-12.200MCE-T is a voltage-controlled temperature-compensated crystal oscillator. It is widely used in applications such as radios, wireless communication systems, navigation systems, and other electronic devices that require precise frequency stability and reliability. In particular, it is suitable for wide-temperature operation and long-term accuracy maintenance. It is also ideal for applications where the oscillator needs to be operated in a very small temperature range.

TC-12.200MCE-T Working Principle

The TC-12.200MCE-T consists of a crystal oscillator, an amplifier, a capacitance to frequency (Cf) converter, a temperature sensor, and an adjustable resistor for frequency trim adjustment. The crystal oscillator works by vibrating at a fixed frequency determined by the cut of the crystal. The amplifier amplifies the signal to the desired output level. The Cf converter converts the output of the amplifier to a corresponding frequency. The temperature sensor measures the temperature and sends an analog signal to the adjustable resistor, which is used to adjust the frequency of the oscillator.

The adjustable resistor adjusts the frequency of the oscillator by effectively changing the capacitance of the Cf converter. The temperature sensor ensures that the oscillator’s frequency remains constant within certain temperature range. This is done by compensating for the frequency variation that occurs due to changes in temperature. The adjusted frequency is then sent to the output terminal as a constant frequency signal.

Conclusion

In conclusion, the TC-12.200MCE-T is a voltage-controlled temperature-compensated crystal oscillator that is used in a variety of applications that require precise frequency stability and reliability. It consists of a crystal oscillator, an amplifier, a Cf converter, a temperature sensor, and an adjustable resistor.
