EEPROM Shift Clock: This signal is the serial shift clock output to the EEPROM.
EEPROM Data In: This signal transfers data from the EEPROM to the Intel
This signal has an integrated pull-up resistor.
EEPROM Data Out: This signal transfers data from the ICH5 to the EEPROM.
EEPROM Chip Select: This signal is the chip select to the EEPROM.
Hub Interface Signals
Hub Interface Strobe First: The first of two differential strobe signals used to
transmit and receive data through the hub interface.
Hub Interface Strobe Second: The second of two strobe signals used to transmit
and receive data through the hub interface.
Hub Interface Impedance Compensation: This signal is used for hub interface
buffer compensation.
Hub Interface Voltage Swing: This is an analog input used to control the voltage
swing and impedance strength of hub interface pins. The expected voltage is
800 mV.
LAN I/F Clock: This signal is driven by the LAN Connect component. The
frequency range is 5 MHz to 50 MHz.
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 LAN Connect component.
LAN Reset/Sync: The platform LAN Connect component’s Reset and Sync
signals are multiplexed onto this pin.
