1 Product Description
The 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 (82545GM for RoHS compliant product) is used, which
supports 10, 100 and 1000 Mbit/s 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/s network connection via a front panel RJ45
connector. The port is galvanically isolated from the Ethernet Controller.
The operating temperature range is 0°C to +70°C.
