1.5 Principle of Operation
Model 78741 consists of one Pentek Model 71741 XMC module mounted on a Pentek
Model 7807 XMC PCI Express carrier, assembled and tested as a single board. It is
ready to plug into computer boards with PCI Express (PCIe®) bus slots. The 71741
XMC has a Pentek−supplied FPGA IP core which includes a multiband Digital
Downconverter (DDC).
The 71741 XMC includes a single−channel 3.6−GHz A/D converter or a two−channel
1.8−GHz A/D converter. Depending on the ADC operating mode (DES or non−DES),
the ADC processes either a single analog input using two A/D channels, or two analog
inputs using separate A/D channels, and sends the digital output from both channels
to the 71741 FPGA as separate data streams. The 71741 FPGA interleaves the two data
streams for processing by the ADC acquisition module and the digital downconverter
core.
The Model 71741 XMC includes GateXpress, a sophisticated FPGA−PCIe configuration
manager for loading and reloading the FPGA. Refer to the Model 71741 Operating Man−
ual, Pentek document 800.71741, for description of GateXpress.
The 71741 includes 4 GBytes of DDR3 SDRAM. This memory is controlled by the FPGA
and is organized as four banks. Separate banks (separate address and data per bank)
allow simultaneous access to all banks. This memory can be used as:
•datacapture
• as buffer memory when transferring data between board resources or to off−board
resources
• a memory resource for custom FPGA applications.
The 7807 Carrier provides one x8 full−duplex PCIe port, allowing high−speed 71741
data transfer to and from the baseboard PCIe bus using the XMC P15 connector. An
optional XMC P16 connector provides two x4 gigabit serial I/O ports to support Xilinx
Aurora, Serial RapidIO, or PCIe interfaces (for Option 105). Two Samtec FireFly™
serial connectors (SER RX, SER TX) are included on the 7807 Carrier, providing access
to both P16 x4 gigabit serial paths from the XMC module. An optional PMC P14 con−
nector provides a data path to a GPIO connector on the carrier PCB (for Option 104).

2.1 Inspection
After unpacking, inspect the unit carefully for possible damage to connectors or com−
ponents. If any damage is discovered, contact Pentek immediately at (201) 818−5900.
Please save the shipping container and packing material in case reshipment is required.
Figure 2−1 illustrates the Model 78741 assembly, with the 71741 XMC module mounted
onto the PCIe carrier.
Note that a cooling assembly/heat sink may be mounted on the 78741 assembly as
shipped from the factory.

2.2 Jumper and Switch Settings
The following sections describe user operating parameters that are set by shorting
jumpers or DIP switches on the Model 78741.
The shorting jumpers used on the Model 78741 are for 0.020" (0.51 mm) square pins
spaced on 0.079" (2.00 mm) centers. These jumpers are NorComp part number 810−
002−LP1R001, or equivalent. Pentek’s part number for these jumpers is 356.00015.
The Model 78741 includes one Pentek 71741 XMC module mounted on a Pentek Model
7807 XMC to PCI Express (PCIe) carrier as illustrated in Figure 2−1 on the prior page.
As shipped, the 71741 XMC module is mounted onto the PCIe carrier.
As shipped from the factory, all jumpers and DIP switches are installed in default posi−
tions on your board. The default operating parameters selected may or may not meet
your requirements. Before installing your Model 78741, please review the following
sections to determine whether you need to change any of these settings.
Refer to Section 2.4 for the switch settings on the Model 71741 PCB. All switch
blocks are accessible in this shipped configuration. Refer to Section 2.6 for the
jumper settings and Section 2.7 for the switch settings on the carrier PCB.
All switch blocks are accessible in the shipped configuration. If you need to access
certain jumpers on the PCIe carrier, you must first remove the XMC module from
the PCIe carrier, as described in Section 2.3.
Note
Do not change jumpers or switches that are not described in this chapter—
those are reserved for factory test and setup purposes only.
