Ethernet

Tews' TPMC883 is a PCI Mezzanine Card (PMC)-compatible module providing a single-channel Gigabit Ethernet 10/100/1000BASE-TX interface.

For highest data rates, the TPMC883 has a 64-bit, 133/100/66-MHz PCI bus interface and is capable of full-speed bus-master DMA operations utilizing maximum PCI bandwidth.

An Intel 82545EM Ethernet controller is used, which supports 10, 100 and 1000 Mbit transmission rates for half and full duplex operation. The TPMC883 is capable of performing an auto-negotiation algorithm which allows both link partners to find out the best link parameters by themselves. The TPMC883 is widely user-configurable via configuration and status-register access over the PCI bus. Front-panel-mounted LEDs indicate various network activities.

The TPMC883-10 provides a 10/100/1000 Mbit network connection via a front-panel RJ45 connector. The port is galvanically isolated from the Ethernet controller.
