1 Product Description
The TXMC387 is a Conduction Cooled Switched Mezzanine Card (CCXMC) 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 TXMC387 are capable of performing an auto-negotiation algorithm which
allows the link-partners to determine the best link parameters. The Ethernet controller on the TXMC387 is
user configurable via configuration and register accesses over the PCIe interface.
LEDs indicate the different network activities.
The TXMC387 routes both Ethernet ports which are galvanically isolated from the Ethernet controllers to the
XMC back I/O P16 connector. On the TXMC387-10R the Ethernet ports are mapped in the X12d range
specified in VITA46.9 standard. The TXMC387-20R maps both Ethernet ports in the X8d range specified in
VITA46.9 standard.
The module meets the requirements to operate in extended temperature range from -40°C to +85°C (Card
Edge Temperature).
