What crystal is used in medical electronics?
2024/07/23
As a common type of electronic components, what are the applications of crystal oscillator in medical electronics? Common medical electronic devices include: intelligent thermometer/gun, blood pressure meter X-ray imaging, AR glasses, magnetic resonance imaging, endoscope, ultrasonic system, visual puncture device, infrared temperature measuring robot, etc.
Then, Xiaobian to explain why medical electronics must use industrial crystal, mainly for the following four reasons:
1, medical electronics itself requirements. Because the biological mechanism of the human body is very complex, medical electronic equipment puts forward higher requirements for electronic components in terms of linearity, mixed signal, micro-electromechanical system and digital signal processing technology.
2. Industrial grade crystal performance. In addition to the well-known accuracy of industrial-grade crystal oscillator, there are actually many invisible parameters that have better stability. For medical electronic applications, more attention should be paid to the stability of electronic system operations.
3, although expensive but good quality. Do technology must consider the quality, plus medical equipment itself for crystal stability requirements are relatively high, do not reduce the cost and reduce product quality. Moreover, how much does it cost to change the civilian grade? If the equipment is abnormal in the later period, the replacement cost is also high. Why not choose the industrial grade crystal oscillator based on the [sensitive word] decision.
4, civil-grade crystal oscillator suppliers are mixed. If the supplier you find is a middleman, it is easy to have second-class products, and the risk is unpredictable! At the same time, the ability to support technology is not available.
