Magnetics Modules for 82547GI(EI) Controller Applications
Carefully select a Gigabit magnetics module for your design. Table 13 lists suggested integrated
magnetics modules for use with the 82547GI(EI) device. These modules also contain integrated
USB jacks. A good quality Gigabit Ethernet controller can also be used with the 82562EZ(EX)
PLC device.
Note: These components are pin-compatible with the magnetics modules shown in Table 9 for the
82562EZ(EX) Platform LAN Connect device.

Power Supplies for the 82547GI(EI) Device
The 82547GI(EI) controller requires three power supplies. The 1.2 V supply must provide
approximately 550 mA current. The 1.8 V supply must provide approximately 230 mA current.
The 3.3 V supply must provide only 5 mA current.
A central power supply can provide all the required voltage sources, or the power can be derived
and regulated locally near the Ethernet control circuitry. Keep in mind that all voltage sources must
remain present during powerdown in order to use the 82547GI(EI) Ethernet controller's LAN wake
up capability. This consideration makes it more likely that at least some of the voltage sources will
be local.
