Intel® 31244 PCI-X to Serial ATA Controller

Routing Guidelines

4.3EMI 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.
