1.5 Principle of Operation
The Model 7341 is a omplete software radio trans eiver suitable for dire t onne tion
to HF or IF ports of a ommuni ations system. Using the PCI board format, the 7341
in ludes two A/D and two D/A onverters.
The 7341 features a Xilinx® Virtex−II Pro™ XC2VP50 Field−Programmable Gate Array.
The FPGA an be pre− onfigured with one of a variety of optional IP ores to provide
signal translation, pro essing and time delay fun tions. In addition to pre− onfigured
fun tions, user− reated FPGA programming is supported by Pentek's GateFlow®
Designer's Kit, Model 4953 Option 140. FPGA I/O onne tions are provided through
the optional PMC P4 onne tor (Option 104).
The 7341 in ludes a large 512−MByte blo k of DDR SDRAM. This memory is on−
trolled by the FPGA and is organized as two 128−MByte banks, 32 Mbyte deep by 32
bits wide and one 256−MByte bank, 64 Mbytes deep and 32 bits wide. Separate banks
(separate address and data per bank) allow simultaneous a ess to all banks. This
memory an be used as buffer memory when transferring data between board resour e
or to off−board resour es.
Dual A/D onverters provide input to a FPGA, where the data an be formatted, pro−
essed or routed to board resour es in luding the GC4016 quad digital down onverter.
The board design provides a dual hannel feedba k path between the FPGA and the
digital down onverter, allowing signals that have been pro essed or time delayed
inside of the FPGA to be sent to the digital down onverter's input.
Dual D/A onverters in lude both interpolation filters and an up onverter stage apa−
ble of produ ing base band I & Q, quadrature modulation, and single−sideband
up onversion analog output.
The 7341 in ludes dual onboard rystal os illators for lo king, but an also a ept
external lo ks through a pair of front panel MMCX onne tors. The PMC is equipped
with a dual LVDS front panel lo k and syn bus that an syn hronize up to eight
modules with built−in master/termination fun tions. The bus format is ompatible
with other Pentek PMC and VIM modules and will work with the Model 9190 Clo k
and Syn Distribution Amplifier for syn hronizing up to 80 modules.

2.1 Inspection
After unpa king, inspe t the unit arefully for possible damage to onne tors or om−
ponents. If any damage is dis overed, onta t Pentek immediately at (201) 818−5900.
Please save the shipping ontainer and pa king material in ase reshipment is required.
The following figure illustrates the omplete Model 7341 assembly as shipped, with the
7141 PMC module mounted onto the PMC to PCI 3U arrier (standard arrier illus−
trated).

2.2 Jumper Settings
The following subse tions over user operating parameters that are set by shorting
jumpers on the Model 7341.
As shipped from the fa tory, jumpers are installed in default positions on your board.
The default operating parameters they sele t may or may not meet your requirements.
Before installing your Model 7341, please review the following subse tions to deter−
mine whether you need to hange any of these settings.
The Model 7341 in ludes one Pentek 7141 PMC module mounted on a PMC to PCI 3U
arrier. Different PCI arriers are used depending on the Option ordered.
Standard − Dynami Engineering model PCI2PMC
Option 703 ( ondu tion− ooled) − A romag ACPC4610CC
These PCI arrier models are illustrated in Figure 2−2 on the next page.
As shipped, the 7141 PMC module is mounted onto the PMC to PCI arrier. Note that
the jumper blo ks on the PMC are lo ated on the omponent side of the PMC, and are
not a essible in this shipped onfiguration. If you need to a ess the jumpers on the
7141 PMC, you must first remove the PMC module from the PCI arrier, as des ribed
in Se tion 2.2.1 (or Se tion 2.2.2 for the Option 703 arrier).
The jumpers on the PMC to PCI arrier have been fa tory set by Pentek for the onfig−
uration shipped.
Note
The user should not change jumpers not identified in these figures—these are
reserved for factory test and setup purposes only.
