These signals can be connected, on the Carrier board, directly to an RJ-45 connector, in order to complete the Ethernet interface.

Please notice that if just a FastEthernet (i.e. 10/100 Mbps) is needed, then only MDI0 and MDI1 differential lanes are necessary.

Unused differential pairs and signals can be left unconnected. Please look to the schematic given as an example of implementation of Gigabit Ethernet connector. In

this example, it is also present GBE_CTREF signal connected on pin #2 of the RJ-45 connector. Intel

analogue powered centre tap, therefore the signal GBE_CTREF is not available on COM Express

while the third one (SATA Channel #2) is managed as a factory option with PCI-e .

All SATA ports support 1.5 Gbps, 3.0 Gbps and 6.0 Gbps data rates.

Here following the signals related to SATA interface:

SATA0_TX+/SATA0_TX-: Serial ATA Channel #0 Transmit differential pair.

SATA0_RX+/SATA0_RX-: Serial ATA Channel #0 Receive differential pair.

SATA1_TX+/SATA1_TX-: Serial ATA Channel #1 Transmit differential pair.

SATA1_RX+/SATA1_RX-: Serial ATA Channel #1 Receive differential pair.

SATA2_TX+/SATA2_TX-: Serial ATA Channel #2 Transmit differential pair.
