GbE Input Clock: This clock is driven by LAN Connect Device. The
frequency will vary depending on link speed.
NOTE: The clock is shared between LAN Connect Interface and
Received Data: The Platform LAN Connect component uses these
signals to transfer data and control information to the integrated
LAN controller. These signals have integrated weak pull-up
resistors.
Transmit Data: The integrated LAN controller uses these signals to
transfer data and control information to the Platform LAN Connect
device.
LAN Reset/Sync: The LAN Connect component’s Reset and Sync
signals are multiplexed onto this pin.
GbE Input Clock: Clock driven by LAN Connect Device. The
frequency will vary depending on link speed.
NOTE: The clock is shared between LAN Connect Interface and
Gigabit LAN Differential Transmit Pair: These signals can,
instead, be used as PCI Express port 6 differential transmit pair
Gigabit LAN Differential Receive Pair: These signals can,
instead, be used as PCI Express port 6 differential receive pair.
Impedance Compensation Output pad: Determines Gigabit
LAN Connect Interface output impedance and bias current.
Impedance Compensation Input pad: Determines Gigabit
LAN Connect Interface input impedance.
GbE Dock/Undock Indication: This signal Indicates if the
platform is in docked or undocked position. The platform should
drive this pin low or high depending on its docked or undocked
state. This signal is configured via soft straps as described in
Section
This signal may instead be used as a GPIO.
