Crystals: 7B-16.000MEEQ-T Application Field and Working Principle

Crystals are a type of resonator composed of a gap cross or a shell and a mechanical diaphragm, both made of special materials. The combination creates a resonant circuit with a nearly perfect frequency, resonance, and capacitance response. 7B-16.000MEEQ-T is a type of crystal that is specifically used for applications that require high precision and stability.

7B-16.000MEEQ-T Application Field

The 7B-16.000MEEQ-T crystal is a general purpose crystal that is used for frequency control over a wide range of applications. Its frequency range extends from 16.000 MHz to 20.148 MHz, making it suitable for a wide range of applications including medical, aerospace, automotive and industrial electronics. It is mainly used for oscillator applications, such as voltage-controlled oscillators (VCOs) and frequency synthesizers. It is also used in radios, television receivers, semiconductor memories, and clock circuitry.

The 7B-16.000MEEQ-T crystal is highly reliable, with a long-term drift rate of 0.15 ppm over a period of one year. Its performance is further enhanced by its extremely low defective part rate of 0.001%. The 7B-16.000MEEQ-T crystal is able to perform reliably in a wide range of temperatures, from -55°C to +85°C. Its robustness allows for extended operation in extreme conditions, such as in high shock and vibration environments. Its hermetically sealed package ensures high reliability even under harsh conditions.

7B-16.000MEEQ-T Working Principle

The 7B-16.000MEEQ-T crystal operates on a fundamental-mode principle. This means that it measures the fundamental frequency of the crystal, rather than any overtone frequency. The crystal is vibrationally coupled to an oscillator, allowing it to resonate at a frequency determined by its cut. The cut is the angle of the faces of the crystal and the diameter of the electrodes. By configuring the cut, crystals can be used to generate exact frequencies.

The 7B-16.000MEEQ-T crystal is a fundamental-mode crystal, meaning that it oscillates in just one direction. This produces an accurate and stable output frequency, regardless of any external influences. The frequency is determined by the size and shape of the crystal, with a wider crystal offering a greater range of frequencies. By exploiting this property, the 7B-16.000MEEQ-T crystal can be used to produce precise oscillations with extremely low frequency drift.

Conclusion

The 7B-16.000MEEQ-T crystal is a type of resonator specifically designed for applications requiring high precision and stability. Its frequency range of 16.000 MHz to 20.148 MHz is versatile enough to be used in a variety of applications, and its long-term drift rate of 0.15 ppm makes it suitable for many extreme environments. It operates on a fundamental-mode principle, meaning that its frequency is determined by the size and shape of the crystal, allowing for precise oscillations with extremely low frequency drift.
