4.3 EMI Considerations
It is highly recommended that good EMI design practices be followed when designing with the
Intel
®
31244 PCI-X to serial ATA controller.
• To minimize EMI on your PCB a useful technique is to not extend the power planes to the
edge of the board.
• Another technique is to surround the perimeter of your PCB layers with a GND trace. This
helps to shield the PCB with grounds minimizing radiation.
