Oscillators are electronic devices that generate a periodic signal without any additional input. One of the most common oscillators used in modern electronics is the TC-12.288MCD-T. This oscillator uses the dynamic capacitance of the single crystal resonator to create the required signal. Let’s take a look at its application field and working principle.

TC-12.288MCD-T can be used in many areas, such as timing control, frequency synthesis, clock generation, and a variety of automotive applications. It has several advantages including wide frequency option, low current consumption, temperature tolerance, and stability. The frequency range of TC-12.288MCD-T oscillator is from 12.288MHz to 12.288KHz and it can be configured with different types of crystal resonators which are mounted in ceramic or metal containers.

The TC-12.288MCD-T oscillator is based on the dynamic capacitance principle of operation. Basically, when a crystal is subjected to an alternating voltage, its capacitance varies with the magnitude of the applied voltage. This performance is used to generate a stable oscillation frequency. Inside the oscillator, a quartz crystal is connected between the collector and the emitter of a transistor. A small DC bias current is passed through the transistor, which will cause the crystal to oscillate. As the frequency depends on the capacitance of the crystal, the oscillator will remain stable.

The oscillator has several circuits to convert the signal into an output signal which can be used to create a clock signal. The first circuit is called the frequency-tuning circuit and its purpose is to adjust the output frequency to the desired frequency. It uses the voltage-controlled crystal oscillator (VCXO) technique and a timing capacitor. The output of the oscillator is connected to the clock divider circuit which is used to divide the frequency by an integer. This circuit is followed by the control logic circuit which is responsible for selecting the desired output signal and the final driver which amplifies the signal.

In summary, the TC-12.288MCD-T oscillator is a commonly used oscillator for different applications. It uses the dynamic capacitance of a quartz crystal to generate an oscillation frequency that is stable and accurate. It uses a variety of circuits to manipulate the signal and generate the desired output. This oscillator is suitable for automotive, timing control, frequency synthesis, and clock generation applications.
