Note:
‡
The total solution power is the total amount of power from the 3.3V supply required for the 82567 to
operate. In its mathematical form:
solution power = (82567 current) * 3.3 V. The 3.3 V is assumed since this is the normal voltage rail provided to the
LAN solution.
Refer to Fig. 2 for details of the implementation of V3.3WOL gated by a FET switch controlled by an OR
of WOL_EN and SLP_M#
Power Delivery
The 82567 operates from two or three external power rails:
• A 3.3 V power rail for internal power regulation and for periphery.
• A 1.8 V-1.9 V power rail for analog functions. (See the 82567 Specification Update
for more information.)
• An optional 1.05 V power rail. Onboard transistor saved/unused when the on-die
LVR is used.
The 1.8 V-1.9 V Rail
The power delivery system supports a load of 300 mA.
The 1.8 V-1.9 V rail is tunable and can be supplied in one of three ways:
• A discrete Switched Voltage Regulator (SVR) solution.
• An external power supply that is not dependent on support from 82567. For
example, the platform designer might choose to route a platform-available 1.8 V-
1.9 V supply to the 82567.
• A discrete LVR solution where the base current of PnP power transistor is driven by
the 82567, while the power transistor is placed externally. 1.9 V is the default
value.
