The TPMC880 is a PCI Mezzanine Card (PMC) compatible module providing a single channel Ethernet Interface and is available in three different configurations: the TPMC880-11 supports a complete Ethernet 10/100Base-T interface, the TPMC880-12 provides an Ethernet 10Base2 (Cheapernet) interface and the TPMC880-10 combines both interface types (10/100Base-T and 10Base2) on one board.

All modules use an Intel 21143-TD Ethernet controller which supports 10 and 100Mb/s transmission rates for half and full duplex operation. The TPMC880-10/11 is capable of performing an auto-negotiation algorithm which allows both link partners to find out the best link parameters by themselves. All TPMC880 are widely user configurable via configuration and status register access over the PCI-bus. All modules have front panel mounted LEDs to indicate various network activities.

The TPMC880-11 provides a 10/100 Mb/s network connection via RJ45 connector. A LXT970A device supports all physical functions on the Twisted-Pair transmission line and is fully IEEE802.3 compliant. The twisted-pair port is galvanically isolated from the LXT970A and the Ethernet controller by an isolation module. The TPMC880-10/12 provides a 10Base2 (Cheapernet) network connection via a BNC connector.

To guarantee overvoltage protection up to 500Vrms the BNC transmission path and the supply voltage is fed over a DC/DC converter and an isolation module to the coax transceiver, which is directly connected to the coax cable. The TPMC880-10 provides a 10Base2 and a 10/100Base-T interface on the same board.
