The TXMC887 is a Switched Mezzanine Card (XMC) compatible module providing a two channel Ethernet 100BASE-TX / 1000BASE-T / 10GBASE-T interface.
The XMC-Connector P15 provides access to the Intel™ X540 dual port 10GbE controller via an x8 PCIe link. Both Ethernet interfaces support 100, 1000 Mbit/s and 10 Gbit/s transmission rates at full duplex operation. The controller is equipped with a 16 Mbit serial flash memory which is accessed by hardware at power-up, which has a firmware area and which can be accessed by software.
The two Ethernet interfaces of the TXMC887 are capable of performing an auto-negotiation algorithm which allows the link-partners to determine the best link parameters. The Ethernet controller on the TXMC887 is user configurable via configuration and register accesses over the PCIe interface.
The TXMC887-10R provides two 100/1000/10000 Mbit/s Ethernet interfaces via front panel RJ45 connectors. Both ports are galvanically isolated from the Ethernet controllers and LEDs indicate the different network activities.
A conduction cooled version, the TXMC387, is also available.
