9.5 Ground Plane Layout
Place a single ground plane approach to
minimize EMI. Bad ground plane partitioning can
cause more EMI emissions that could make the
network interface card (NIC) not compliant with
specific FCC part 15 and CE regulations.
The ground plane must be separated into Analog
ground domain and Digital ground domain. The
line which connects the analog ground domain
and digital ground domain should be far away
from the AGND pins of DM9102D (see Figure
9-4-1).
All AGND pins (pin 100, 107, 108) could not
directly short each other (see Figure 9-4-3). It
must be directly connected to the analog ground
domain (see Figure 9-4-2).
The analog ground domain area is as large as
possible
