YXC车规级晶振在倒车雷达中的应用

With the continuous development of technology, cars are no longer just a simple transportation, but comprehensive electronic products that combine a variety of advanced technologiesTaste.Crystals are widely used in various sensors, controllers and actuators in the automotive safety and comfort system.For example, the vehicle navigation system requires the crystal to provide accurate time benchmark; the engine control system depends on the crystal to perform real -time control; when the airbag system collides, the crystal provides a trigger signal.In addition, crystal also plays an irreplaceable role in emerging fields such as connected to the Internet and autonomous driving.With the advent of the 5G era in recent years, the development of smart cars has become more and more rapid.Therefore, the market demand for crystal components in automotive electronic components will continue to grow.

Focus on the application of crystal crystal in reversing radar

The application of crystal in the reversing radar

The working principle of reversing radar is mainly to use ultrasonic.The reversing radar transmits the ultrasonic of the reflection through the ultrasonic, and then receives the reflected ultrasonic, and determines the distance and location of the obstacles based on the time and strength of the ultrasonic backproof.                 

Crystal provides a reference clock for the reversing radar MCU, which is the key to realizing crystal detection and early warning of reversing radar
