Selection Guide for on-board special crystal oscillator

At present, the crystal oscillators selected by the vehicle special crystal oscillator industry are getting smaller and smaller. The overall packaging of crystal products is developing in the direction of miniaturization. The crystal oscillator requirements of consumer electronic products such as crystal oscillator and mobile phone used in general automobile are much higher, and the working environment of automobile manufacturing is higher than that of general consumer products. The NDK crystal oscillator has achieved the requirements of the vehicle industry. In the global vehicle specific crystal oscillator industry, NDK crystal oscillator is the crystal oscillator manufacturer with the highest share in the automotive electronics field, and enjoys high popularity and reputation in the industry. The global vehicle mounted crystal oscillator industry accounts for more than 60%.
The index requirements of automotive electronics for crystals mainly include the following:
1. Wide range of operating temperature (- 40 - + 125 ° C, up to 150 ° C in some applications);
2. It has stable starting vibration characteristics under extremely severe environmental conditions;
3. It has excellent characteristics such as heat resistance, anti vibration and impact resistance;
4. Comply with aec-q200 standard;
5. High quality requirements such as zero defects.
Automotive electronics mainly uses the system of on-board special crystal oscillator:
1. The safety control system includes: engine control, steering by wire system, transmission, airbag, anti lock braking system, tire pressure detection system and electric power steering system.
2. The information and intelligence system includes: car audio, on-board navigation system, data bus system, surveillance camera, reversing radar and high security wire control system.
3. Intelligent transportation system
4. Body system, automobile clock, timer, instrument panel, wireless remote control door lock, automobile air conditioning, automatic window control, automobile anti-theft system.
