Ethernet

Tews' TPMC882 is a PCI Mezzanine Card (PMC)-compatible module providing a four-channel Ethernet 10BASE-T/100BASE-TX interface.

A transparent 32-bit 66-MHz PCI-to-PCI Bridge provides access to the four Intel 82551IT Ethernet controllers, which support 10 and 100Mbit transmission rates for half and full duplex operation. Each channel of the TPMC882 is capable of performing an auto-negotiation algorithm which allows both link partners to find out the best link parameters by themselves. The TPMC882 is widely user-configurable via configuration and status-register access over the PCI bus.

The TPMC882-10 provides four 10/100Mbit network connections via front panel RJ45 connectors. The TPMC882-11 routes all four Ethernet ports to the back I/O P14 connector. The ports are galvanically isolated from the Ethernet controller.
