1.5 Principle of Operation
The Model 7342 is a complete software radio transceiver suitable for direct connection
to HF or IF ports of a communications system. Using the popular PMC module format,
it includes four A/D and one D/A converters.
The 7342 features a Xilinx® Virtex−4 XC4VSX55 FPGA (XC4VLX100 with Option 110)
and a Xilinx Virtex−4 XC4VFX60 FPGA (XC4VFX100 with Option 100). The XC4VSX55
(or XC4VLX100) FPGA, identified as the “Signal FPGA” in this manual, can be pre−
configured with one of a variety of optional IP cores to provide signal translation, pro−
cessing, and time delay functions. In addition to pre−configured functions, user−cre−
ated FPGA programming is supported by Pentek's GateFlow® Designer's Kit, Model
4953 Option 142. The XC4VFX60 (or XC4VFX100) FPGA, identified as the “PCI FPGA”
in this manual, provides board interfaces including PCI. PCI FPGA I/O connections
are provided through the optional PMC P4 connector (Option 104).
Four A/D converters provide input to the Signal FPGA, where the data can be format−
ted, processed or routed to board resources.
The D/A converter includes both interpolation filters and an upconverter stage capable
of producing baseband I & Q or quadrature modulation analog output.
The 7342 includes a large 768−MByte block of DDR2 SDRAM. This memory is con−
trolled by the Signal FPGA and is organized as three 256−MByte banks, 32 Mbyte deep
by 32 bits wide. Separate banks (separate address and data per bank) allow simulta−
neous access to all banks. This memory can be used as buffer memory when transfer−
ring data between board resource or to off−board resources.
The 7342 includes dual onboard crystal oscillators for clocking, but can also accept
external clocks through a front panel MMCX connector. The 7342 is equipped with a
dual LVDS front panel clock and sync bus that can synchronize up to eight modules
with built−in master/termination functions. The bus format is compatible with other
Pentek PMC and VIM modules and will work with the Model 9190 Clock and Sync
Distribution Amplifier for synchronizing up to 80 modules.

Chapter 2: Installation and Connections
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.
See Figure 2−1, on the next page, for a drawing of the Model 7342 assembly as shipped.
2.2 Jumper Block Settings
The following subsections cover user operating parameters that are set by shorting
jumpers on the Model 7342.
The term jumper (or jumper block) refers to a group of two or more pins on a circuit
board that may be connected in pairs by a shorting jumper to set or change an operat−
ing characteristic of the board. A pair of pins connected in this manner are referred to
as installed, or shorted. A pair of pins that are not connected are called removed, or
open. The shorting jumpers used on the Model 7342 are for 0.020" (0.51 mm) square
pins spaced on 0.079" (2.00 mm) centers. These jumpers are DuPont™ part number
86730−001, or equivalent. Pentek’s part number for these jumpers is 356.00010.
As shipped from the factory, jumpers are installed in default positions on your board.
The default operating parameters they select may or may not meet your requirements.
Before installing your Model 7342, please review the following subsections to deter−
mine whether you need to change any of these settings.
The Model 7342 includes one Pentek 7142 PMC module mounted on a Dynamic Engi−
neering Model cPCI2PMC PMC to cPCI 3U carrier. The jumpers on this PMC to cPCI
carrier have been factory set by Pentek for the configuration shipped.
As shipped, the 7142 PMC module is mounted onto the PMC to cPCI carrier. Note that
all jumpers on the PMC are located on the component side of the PMC, and are not
accessible in this shipped configuration. See Section 2.2.3 for the jumper settings for the
7142 PMC. If you need to access a jumper on the 7142 PMC, you must first remove the
PMC module from the cPCI carrier, as described in Section 2.2.1.
Note
The user should not change jumpers not identified in these figures—these are
reserved for factory test and setup purposes only.
