Pinouts and Signal Descriptions
Description
Gigabit Ethernet Controller 0: Media Dependent Interface
Differential Pairs 0, 1, 2, 3. The MDI can operate in 1000,
100, and 10Mbit/sec modes. Some pairs are unused in
some modes according to the following:
1000BASE-T 100BASE-TX 10BASE-T
MDI[0]+/- B1_DA+/-
MDI[1]+/- B1_DB+/-
MDI[2]+/- B1_DC+/-
MDI[3]+/- B1_DD+/-
Gigabit Ethernet Controller 0 activity indicator, active low.
Gigabit Ethernet Controller 0 link indicator, active low.
Gigabit Ethernet Controller 0 100Mbit/sec link indicator,
active low.
Gigabit Ethernet Controller 0 1000Mbit/sec link indicator,
active low.
Reference voltage for Carrier Board Ethernet channel 1
and 2 magnetics center tap. The reference voltage is
determined by the requirements of the Module PHY and
may be as low as 0V and as high as 3.3V. The reference
voltage output shall be current limited on the Module. In
the case in which the reference is shorted to ground, the
current shall be 250 mA or less.
