Crystals: 7M-16.000MEEC-T Application Field and Working Principle

Crystals, also known as mechanical resonators, are among the earliest electronic components. They are used to control the frequency, such as radio and television transmission, navigation, and instrumentation, and form an important part of a wide range of electronic and electrical products.The 7M-16.000MEEC-T crystal is one of the most commonly used quartz crystals for general-purpose applications in the electronics industry. It has the characteristics of high frequency stability, low temperature drift and small volume. It has a wide range of applications, such as mobile communication, communication network systems, automotive electronics, medical electronics and electronic instruments.This type of crystal is composed of a quartz crystal and an AT-cut or SC-cut crystal oscillation board. The AT-cut crystal oscillation board is constructed and assembled with a quartz plate, an oscillatory plate, a terminal plate and a supporting plate and is mounted on the SLA key pin of the PCB. It has the advantages of small size, good accuracy, wide range, stable operation, low temperature drift and small temperature coefficient.The principle of the crystal oscillator is based on the piezoelectric effect. Piezoelectric crystals have the property of exhibiting electrical charge when they undergo mechanical deformation. When an electric field is applied to such a crystal, it will deforms and generates a displacement field, and a time-dependent electric potential is generated as a result. If this electric potential is put back on the crystal, it will defrom continuously, due to the loss of energy, until the electric field is removed. When an external alternating current is applied to the crystal, it will vibrate at the same frequency as the external stimulation, and the total impedance of the circuit remains unchanged. This oscillation mechanism is known as the piezoelectric effect.The working principle of a 7M-16.000MEEC-T crystal is based on the idea that its piezoelectric effect causes the crystal to vibrate at a specific frequency, known as its resonance frequency. The crystal oscillator consists of two or three components: a quartz crystal and a circuit connection board or a series of components such as inductance and capacitance. When the alternating signal of a certain amplitude and frequency is applied to the crystal, it will vibrate and become a periodic vibration. This period oscillation signal is separated by the connecting circuit board, and the vibration frequency is fiited to the frequency of the signal applied. The output signal of the crystal is a pure sinusoidal signal of constant amplitude and frequency.The 7M-16.000MEEC-T crystal has a number of common applications in the electronics industry including timing control in alarm systems, clock frequency generators and as an oscillator in radio frequency receivers. It can also be used as a frequency reference for measurement of frequency in telecommunications and computer systems. In addition, the crystal can be used in quartz watches, clocks, temperature and pressure controllers and other products as well.In conclusion, the 7M-16.000MEEC-T crystal is a widely used quartz crystal for general purpose applications with a number of applications widely found in many electronic products. It has the advantage of stability, low temperature drift, small size and acceptable accuracy. Its overall performance and stability have made it one of the most widely used components in many electronic and electrical products.
