Application Information

The TCP886 is a 3U 32bit/64bit CompactPCI module providing a four channel M12 Industrial Ethernet 10BASE-T / 100BASE-TX interface.

The TCP886 is equipped with a transparent PCI/PCI-X to PCIe Bridge which is capable of performing data transfer with a bus width of up to 64 bit at bus frequencies of up to 133 MHz depending on the product order option and the system backplane configuration.

The Bridge and a PCIe Switch provide access to the Intel 82574IT Fast Ethernet controllers. Each Ethernet interface supports 10 and 100 Mbit/s transmission rates for full duplex and half duplex operation and is equipped with a 32 Kbit Serial EEPROM.

The four front panel D-coded M12 connector Ethernet interfaces of the TCP886 are capable of performing an auto negotiation algorithm which allows both link-partners to find out the best link-parameters by themselves.

The TCP886 is widely user configurable via configuration and status register access over the CompactPCI bus. All ports are galvanically isolated from the Ethernet controllers and LEDs indicate network activities.

On the TCP886-10R only CompactPCI connector J1 is fitted which means that the module is limited to 32bit PCI bus width.

The TCP886-20R is additionally equipped with CompactPCI connector J2 which allows 64bit data transfer in a corresponding backplane system configuration.

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