2.4 VME Bus Interface
The TVME8240 uses the Universe-II VME PCI Bridge (Tundra) to build the VME interface.
The Universe-II VME PCI Bridge provides a 32 bit address / 32 bit data VME interface.
Please refer to the Universe-II manuals for details.
2.5 LAN Interface
The TVME8240 uses the 21143 10/100Base-TX Ethernet LAN Controller (Intel) with the LXT970 Fast
Ethernet Transceiver (Intel) on its MII interface to build the Ethernet interface.
A 10/100Base-TX Ethernet interface is available on an 8P RJ45 connector on the front panel.
A 10Base-T AUI interface is available at the VME P2 connector.
Please refer to the 21143 and LXT970 manuals for details.
2.6 IP Bus Interface
The TVME8240 uses a XC2S100 FPGA (Xilinx) for the IndustryPack interface logic.
The TVME8240 uses the PCI9030 PCI Target Chip (PLX Technologies) to access the IndustryPack
FPGA from the PCI bus.
Four single-sized IP slots (A–D) are provided. Double-sized IP modules (16 bit) can be used on
combined IP slots A/B or C/D. The clock rate for each IP slot is programmable to be 8 MHz or 32 MHz.
Please refer to the IP interface section for details.
2.7 PCI Expansion Interface
The TVME8240 provides a 114-pin PCI expansion connector for using existing VME PCI Expansion
Boards (e.g. TEWS TECHNOLOGIES’ TVME230 IP-Span or Motorola PMC-Span).
