It has low power consumption, making it suitable for applications powered by batteries, such as clocks, car navigation, mobile phones, and other portable devices. Its ultra-miniature size and lightweight design make the TA-3.6864MDE-T ideal for situations where space is a premium, such as space exploration or embedded systems. Additionally, the TA-3.6864MDE-T is highly reliable and suitable for military and industrial applications.

Working Principle

The TA-3.6864MDE-T utilizes the piezoelectric effect of a quartz crystal resonator. Piezoelectricity is the phenomenon in which a crystal polarizes when mechanical stress is applied to it, and conversely, when a voltage is applied to the crystal it begins to vibrate. This vibration is kept in a state of resonance by electrically connecting the crystal to a feedback circuit.

The TA-3.6864MDE-T comprises of a quartz crystal housed in a metal enclosure with two pins, which are connected to an external oscillating circuit that is designed to provide negative feedback to the crystal. A signal is fed into the crystal, and the signal reflected back is compared with the original signal. Any differences in the waveform of the two signals are then amplified and fed back to a control electrode.

This process results in a tuned circuit that produces an oscillating waveform of a very precise frequency. The frequency is determined by the crystal which is cut and smashed to a specific length (dependent on the frequency required). The two pins on the oscillator act as a connection point for this circuit, so that the precise frequency can be connected to the external circuit.

In summary, the TA-3.6864MDE-T is a quartz crystal oscillator, operating on the principle of piezoelectricity. It has a wide range of applications thanks to its precise frequency determined by the crystal resonator, and its low power consumption and ultra-miniature size.
