PCIE_​C2_​TX_​P/GbE_​TX_​P

PCIE_​C2_​TX_​N/GbE_​TX_​N

O

Differential transmit pairs to the Intel® Ethernet Connection I219 based on the PCIe interface.

All Processor Series

PCIE_​C2_​RX_​P/GbE_​RX_​P

PCIE_​C2_​RX_​N/GbE_​RX_​N

I

Differential receive pairs to the Intel® Ethernet Connection I219 based on the PCIe interface.

All Processor Series

GPP_​C04/SML0DATA

I/OD

System Management Link data signal interface to Intel® Ethernet Connection I219.

Note:The Intel® Ethernet Connection I219 connects to SML0DATA signal.
All Processor Series

GPP_​C03/SML0CLK

I/OD

System Management Link data signal interface to Intel® Ethernet Connection I219.

Note:The Intel® Ethernet Connection I219 connects to SML0CLK signal.
All Processor Series

GPP_​V10/LANPHYPC

O

LAN PHY Power Control: LANPHYPC should be connected to LAN_​DISABLE_​N on the PHY. Processor will drive LANPHYPC low to put the PHY into a low power state when functionality is not needed.

Note:LANPHYPC can only be driven low if SLP_​LAN# is de-asserted.
All Processor Series

GPP_​V11/SLP_​LAN#

IO

LAN Sub-System Sleep Control: If the Gigabit Ethernet Controller is enabled, when SLP_​LAN# is de-asserted it indicates that the PHY device must be powered. When SLP_​LAN# is asserted, power can be shut off to the PHY device.

Note:If Gigabit Ethernet Controller is statically disabled via BIOS, SLP_​LAN# will be driven low.
All Processor Series

GPP_​V02/SOC_​WAKE#

I

SOC_​WAKE: LAN Wake Indicator from the GbE PHY.

Note:SOC_​WAKE# functionality is only supported with Intel PHY I219. Connection of a third party LAN device’s wake signal to SOC_​WAKE# is not supported.
