Gigabit Ethernet signals
Gigabit Ethernet interface is realized on SM-B69 module by using an Intel I210 Ethernet contoller, which is interfaced to Intel processor through a PCI interface.
Here following the signals involved in Gigabit Ethernet #0 management:
GB/GBE0_MDI0-: Media Dependent Interface (MDI) Transmit/Receive differential pair
GB/GBE0_MDI1-: Media Dependent Interface (MDI) Transmit differential pair
GB/GBE0_MDI2-: Media Dependent Interface (MDI) Transmit differential pair
GB/GBE0_MDI3-: Media Dependent Interface (MDI) Transmit differential pair
GBE0_LINK_ACT#: Ethernet controller activity indicator. Active Low Output signal, +3.3V_ALW electrical level
GBE0_LINK100#: Ethernet controller 100Mbps link indicator. Active Low Output signal, +3.3V_ALW electrical level
GBE0_LINK1000#: Ethernet controller 1Gbps link indicator. Active Low Output signal, +3.3V_ALW electrical level
GBE0_SDP: Software defined pin, directly managed by Intel® Ethernet Controller I210 for Gigabit Ethernet #0
Here following the signals involved in Gigabit Ethernet #1 management:
GB/GBE1_MDI0-: Media Dependent Interface (MDI) Transmit/Receive differential pair
GB/GBE1_MDI1-: Media Dependent Interface (MDI) Transmit differential pair
GB/GBE1_MDI2-: Media Dependent Interface (MDI) Transmit differential pair
GB/GBE1_MDI3-: Media Dependent Interface (MDI) Transmit differential pair
GBE1_LINK_ACT#: Ethernet controller activity indicator. Active Low Output signal, +3.3V_ALW electrical level
GBE1_LINK100#: Ethernet controller 100Mbps link indicator. Active Low Output signal, +3.3V_ALW electrical level
