Description
P0_MDIP[0]
P0_MDIN[0]
Media Dependent Interface[0].
In 1000BASE-T mode in MDI configuration, MDIP/N[0] correspond to BI_DA±.
In MDIX configuration, MDIP/N[0] correspond to BI_DB±.
I/O
In 100BASE-TX and 10BASE-T modes in MDI configuration, MDIP/N[0] are used
for the transmit pair. In MDIX configuration, MDIP/N[0] are used for the receive
pair.
Unused MDI pins must be left floating.
The I347-AT4 contains an internal 100 Ω resistor between the MDIP/N[0] pins.
P0_MDIP[1]
P0_MDIN[1]
Media Dependent Interface[1].
In 1000BASE-T mode in MDI configuration, MDIP/N[1] correspond to BI_DB±. In
MDIX configuration, MDIP/N[1] correspond to BI_DA±.
I/O
In 100BASE-TX and 10BASE-T modes in MDI configuration, MDIP/N[1] are used
for the receive pair. In MDIX configuration, MDIP/N[1] are used for the transmit
pair.
Unused MDI pins must be left floating.
The I347-AT4 contains an internal 100 Ω resistor between the MDIP/N[1] pins.
P0_MDIP[2]
P0_MDIN[2]
Media Dependent Interface[2].
In 1000BASE-T mode in MDI configuration, MDIP/N[2] correspond to BI_DC±. In
I/O
MDIX configuration, MDIP/N[2] correspond to BI_DD±.
In 100BASE-TX and 10BASE-T modes, MDIP/N[2] are not used.
Unused MDI pins must be left floating.
The I347-AT4 contains an internal 100 Ω resistor between the MDIP/N[2] pins.
P0_MDIP[3]
P0_MDIN[3]
Media Dependent Interface[3].
In 1000BASE-T mode in MDI configuration, MDIP/N[3] correspond to BI_DD±.
In MDIX configuration, MDIP/N[3] correspond to BI_DC±.
I/O
In 100BASE-TX and 10BASE-T modes, MDIP/N[3] are not used.
Unused MDI pins must be left floating.
The I347-AT4 contains an internal 100 Ω resistor between the MDIP/N[3] pins.
