The
electromagnetic interference
designs. National’s patented EMI reduction technology offers low EMI emissive clock
circuitry, EMI-optimized pinouts, gradual turn-on output drivers (GTOs) and an on-chip
choke device to help circumvent many of the EMI issues influencing embedded control
designs. National has achieved 15-20 dB reduction in EMI transmissions when designs
have incorporated its patented EMI reducing circuitry (Figure 2-34).
