YXC Automotive Resonator 8MHz, load 20PF, Operating Temperature -40~125℃, Used in Vehicle Reversing Radar
Reversing radar, also known as "reversing anti-collision radar", also known as "parking assist device", is a safety assist device for parking or reversing a car.
It is mainly composed of ultrasonic sensors, controllers and displays, etc. It can inform the driver of obstacles around it through sound or more intuitive display, relieve the driver's troubles when parking, reversing, and starting the vehicle, and help the driver eliminate the defects of blindness and blurred vision.
In the reversing radar system, the passive crystal oscillator is used as a clock source to control the working rhythm of each module of the radar system. The crystal oscillator generates a stable oscillation signal, which is used by the divider and timing control circuit to determine the time interval between sensor scanning and data processing.
In addition, the frequency of the crystal oscillator will be selected and adjusted according to specific requirements to meet the accurate measurement needs of the reversing radar system. If the crystal oscillator frequency is inaccurate or there is jitter, it will lead to an increase in measurement errors or misalignment of data processing, thereby affecting the accuracy and reliability of the reversing radar.
Therefore, the crystal oscillator plays a key role in the vehicle reversing radar. It ensures that the various components of the system work in the correct time sequence to achieve accurate distance measurement and obstacle detection functions.
The XC2SO-114-8M material in the YSX321SC series of passive crystal oscillators launched by YXC, the following are the typical parameters of XC2SO-114-8M in the application characteristics of vehicle-mounted reversing radar:
1. Automotive-grade passive crystal oscillator, in line with AEC-Q200 industry certification, high reliability, shock resistance;
2. The operating temperature is high temperature -40~125°C, which is different from the industrial-level automotive-grade reliability test, and meets high and low temperature tests, temperature shock tests, etc.;
3. Widely used in automotive electronics applications, used in ADAS systems such as millimeter-wave radar, laser radar, reversing radar, ultrasonic radar, etc.
YXC automotive resonator YSX321SC series, frequency is 8MHz, total frequency difference ±80PPM, the following is the YSX321SC series specification.
