Page 6: Product Description
32 Kbit serial EEPROM. The four Ethernet interfaces of the TXMC885 are capable of performing an auto negotiation algorithm which allows both link-partners to find out the best link-parameters by themselves. The TXMC885 is widely user configurable via configuration and status register access over the PCI Express interface. -

Page 8: Pci Device Topology On Txmc885
PCI Device Topology on TXMC885 The TXMC885 uses four Gigabit Ethernet Controllers (Intel 82574IT) each communicating via a PCIe Rev. 1.1 compliant x1 Interface. To be able to access the Ethernet controllers they are connected to the x1 Downstream Ports of a PCIe Switch (IDT 89HPES8T5A). The x4 Upstream Port of the Switch is connected to the XMC Connector communicating with the host system. -
