4.11 Ethernet Connectors

The KTUS15 board support 1 channel of 10/100/1000Mb Ethernet using the Intel® 82574L PCI express LAN

controller.

In order to achieve the specified performance of the Ethernet port, Category 5 twistedpair cables must be

used with 10/100MB and Category 5E, 6 or 6E with 1Gb LAN networks.

The signals for the Ethernet ports are as follows:

Signal

Description

MDI[0]+ / MDI[0]- In MDI mode, this is the first pair in 1000Base-T, i.e. the BI_DA+/- pair, and is the

transmit pair in 10Base-T and 100Base-TX.

In MDI crossover mode, this pair acts as the BI_DB+/- pair, and is the receive pair

in 10Base-T and 100Base-TX.

MDI[1]+ / MDI[1]- In MDI mode, this is the second pair in 1000Base-T, i.e. the BI_DB+/- pair, and is

the receive pair in 10Base-T and 100Base-TX.

In MDI crossover mode, this pair acts as the BI_DA+/- pair, and is the transmit

pair in 10Base-T and 100Base-TX.

MDI[2]+ / MDI[2]-

In MDI mode, this is the third pair in 1000Base-T, i.e. the BI_DC+/- pair.

In MDI crossover mode, this pair acts as the BI_DD+/- pair.

MDI[3]+ / MDI[3]-

In MDI mode, this is the fourth pair in 1000Base-T, i.e. the BI_DD+/- pair.

In MDI crossover mode, this pair acts as the BI_DC+/- pair.

Note: MDI = Media Dependent Interface.
