FPGAs
The Model 7858 includes one 7158 PMC module that has two Xilinx Virtex−5 FPGAs
for signal interfaces and processing:
• Processing FPGA − Provides signal translation, processing, and time delay functions.
• PCI Interface FPGA − Provides board interfaces, including PCI−X.
Following are FPGA considerations:
• Supported Processing FPGAs: The Processing FPGA can be populated with a
variety of different FPGAs to match the specific requirements of the processing task.
Supported FPGAs include:
• Supported PCI Interface FPGAs:
• FPGA I/O through the P14 Connector (Option 104): Option −104 adds the P14 PMC
connector with 16 pairs of LVDS connections to the Processing FPGA and 16 pairs of
LVDS connections to the Interface FPGA for custom I/O. For more information, refer
to Section 2.7.4 in the Pentek Model 7858 Installation Manual.
• Heat Sinks (Option 73x): Because the 7158 series can have complex programming in
large FPGAs, the power dissipation can exceed 30W. Because of this, Pentek provides
several two−slot heat sink options with superior cooling capabilities relative to the
standard, single−slot heat sink. The following heat sink options are available.
• JTAG Expansion Assembly: The Model 9269 JTAG expansion assembly provides
several LEDs and connectors, which provide access to both FPGAs for JTAG
functions, and access to the PowerPC in the Processing FPGA for Ethernet and RS232
I/O. The Model 9269 is usually just plugged into the J1 connector on the 7158 PCB.
However it is also possible to mount the JTAG board permanently to the 7158 PCB.
Call Pentek for further details. For more information about the JTAG assembly, refer
to Section 2.5 of the Pentek Model 7158 Operating Manual (800.71580).
