Application Information

The TPMC885 is a PCI Mezzanine Card (PMC) compatible module providing a dual or four channel Ethernet 10BASE-T / 100BASE-TX / 1000BASE-T interface.

A transparent 64 bit, up to 133 MHz PCI-X/PCI to PCIe Bridge and a PCIe Switch provide access to the Intel 82574IT Gigabit Ethernet controllers. Each Ethernet interface supports 10, 100 and 1000 Mbit/s transmission rates for full duplex operation, 10 and 100 Mbit/s transmissions for half duplex operation, and is equipped with a 32 Kbit Serial EEPROM.

The two/four Ethernet interfaces of the TPMC885 are capable of performing an auto negotiation algorithm which allows both link-partners to find out the best link-parameters by themselves. The TPMC885 is widely user configurable via configuration and status register access over the PCI bus.

The TPMC885-10R provides four 10/100/1000 Mbit/s Ethernet connections via front panel RJ45 connectors.The TPMC885-11R routes four Ethernet ports to the back I/O P14 connector without any RJ45 connector at the front.

The TPMC885-20R provides two 10/100/1000 Mbit/s Ethernet connections via front panel RJ45 connectors.

The TPMC885-21R routes two Ethernet ports to the back I/O P14 connector without any RJ45 connector at the front.

All ports are galvanically isolated from the Ethernet controllers and LEDs on the board indicate the different network activities.

The module meets the requirements to operate in extended temperature range from -40° to +85°C.
