| Features |
igns have to meet standards set by regulatory agencies. Two standards are, FCC (Federal Communications Commission) regulations part 15B, and International Electrotechnical Commission’s International Special Committee on Radio Interference (CISPR) 22B. These regulations specify limits:
Most PC manufactures are required to meet these EMI testing requirements for system level design. Because of the regularity/repetition of the clock signals, the clock synthesis (CK100) and clock buffer (CKBF) in the 440BX (CK97 specification from Intel) designs create a significant amount of noise and EMI. The C... |
