EMC를 고려한 고속 PCB의 SI해석 기법 연구

Today, the stability control of the automotive electronic components and its new technology are being developed rapidly. Generally, the AVN system that can support various media such as DMB, MP3 and MPEG4 are powered by the battery of the car that has not been stabilized and the fluctuations in the battery input may result in poor quality of the sound and video output stream. To solve this problem, EMC test is conducted to the AVN system and the system is re-designed if the requirements in the EMC standard are not met. This paper presents SI(Signal Integrity) analysis techniques to secure reliability and stable functionality from fluctuating input from the battery. Some of the techniques of SI analysis include CE(Conducted Emission), RE(Radiated Emission), Cross-talk and SSN(Simultaneous Switching Noise), and these techniques are used to analyze operational characteristics to minimize the functional error by considering the CPU, DDR2 memory and its address.
