1.5 Principle of Operation
The Model 7642 is a complete software radio transceiver suitable for direct connection
to HF or IF ports of a communications system. Using the popular PCI board format, it
includes four A/D and one D/A converters.
The 7642 features a Xilinx® Virtex−4 XC4VSX55 FPGA (XC4VLX100 with ption 110)
and a Xilinx Virtex−4 XC4VFX60 FPGA (XC4VFX100 with ption 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 ption 142. The XC4VFX60 (or XC4VFX100) FPGA, identified as the “PCI FPGA”
in this manual, provides board interfaces including PCI. PCI FPGA I/ connections
are provided through the optional PMC P4 connector ( ption 104).
The 7642 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.
Four A/D converters provide input to a Signal FPGA, where the data can be formatted,
processed or routed to board resources.
The D/A converter includes both interpolation filters and an upconverter stage capable
of producing baseband I & Q and quadrature modulation analog output.
The 7642 includes dual onboard crystal oscillators for clocking, but can also accept
external clocks through a front panel MMCX connector. The 7642 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 modules and will work with the Model 9190 Clock and Sync Distribution
Amplifier for synchronizing up to 80 modules.

2.2 Jumper and Switch Settings
The following subsections cover user operating parameters that are set by shorting
jumpers or dip switches on the Model 7642.
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 7642 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, several 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 7642, please review the following subsec−
tions to determine whether you need to change any of these settings.
The Model 7642 assembly consists of two modules, a Pentek 7142 PMC module and a
PMC to PCI adapter board (Technobox™ Model 5012). See Section 2.2.4 for description
of the jumper settings on the 3674 PCI adapter board.
As shipped, the 7142 PMC module is mounted onto the PCI adapter. Note that all
jumpers on the PMC are located on the component side of the PMC, and are not acces−
sible in this shipped configuration. See Section 2.2.3 for the jumper settings for the 7142
PMC. If you need to access this jumper on the 7142 PMC, you must first remove the
PMC module from the PCI adapter board, as described in Section 2.2.1.
Note
The user should not change jumpers or switches not described in this
chapter—those are reserved for factory test and setup purposes only.

2.3 Installing the Pentek JTAG PC Assembly
If you need to use JTAG connections to the Model 7642 (e.g., to download code to the
configuration EEPR Ms or to the PowerPC core), a special JTAG connector PC assem−
bly, Pentek part # 004.71402, must be mounted onto the 7142 PMC board. This unit
may be mounted onto the 7142 while the PMC module is attached to the PCI adapter.
An assembly drawing of the Model 7642 is provided below, showing the JTAG PC
assembly mounting orientation.
To mount the JTAG PC assembly onto the 7642:
1) First remove the two flat−head mounting screws that secure the Model 7642 PCB to
the PCI adapter standoffs.
2) Plug the JTAG PC assembly into the connector J1 on the 7642 (see figure above), and
secure to the 7642 and PCI adapter using the two captive screws on the JTAG board.
The JTAG J2 and J3 connectors are described on the next page.

2.4 Installing the Model 7642 in a Personal Computer
Pentek's Model 7642 is designed to operate in personal computers that support the Intel
PCI Bus standard. This card cannot be used in computers equipped with the VESA
local bus, nor in those machines that provide only ISA or EISA expansion slots.
Refer to Figure 2−1 on page 9 for illustration of the complete Model 7642 assembly.
1) rient the personal computer on your static−controlled work surface such that the
rear panel faces you.
2) Remove the cover from the computer, to gain access to the PC's motherboard and its
local bus connectors.
3) PCI Bus connectors are usually white in color (as opposed to ISA bus connectors
which are usually black, and VESA connectors which are usually brown), and are
about 3½" long. Select a vacant PCI connector in which to install the Pentek 7642
assembly, and remove the blank expansion slot cover plate on the computer's rear
panel located immediately to the RIGHT of the selected connector (this also differs
from ISA expansion cards, where the rear panel is mounted to the left of the card).
4) Before touching the Model 7642 assembly, touch the case of your computer's power
supply, to discharge any static electrical charge that may have accumulated on you.
Then, remove the 7642 assembly from its anti−static packaging, and install the card's
connecting edge into the selected PCI expansion socket. (See Figure 2−7 on the next
page.)
Be certain that the card edge is properly aligned with the PCI connector. Gentle
downward pressure should be sufficient to fully seat the card edge in the connector.
DO NOT ATTEMPT TO ORCE THE CARD INTO THE SLOT! If excessive force
is necessary, then the card is probably misaligned. Damage to either the PC
motherboard or the 7642 will be the most likely result of attempts at forced
installations.
5) After the assembly is fully and properly seated in the PCI connector, secure the card's
rear panel to the computer's chassis.
6) The Model 7642 board has a 4−pin power connector to supply the majority of power
to the components. This is a standard disk drive power connector used in PCs. Plug
a spare power connector from your PC’s power supply into this PCB connector.
C UTION
Perform this installation at a static−controlled work workstation.
Disconnect all power from the PC before attempting to install this board.

7) The cover may now be replaced and power may be reconnected.
This completes the installation procedure.
Note that the Model 7642 provides a 96−pin DIN connector at the edge of the PCB. The
‘A’ and ‘C’ rows of this connector are routed to PCI FPGA spare pins on the board.
This is used with Model 7642 ption 104, described in Section 2.5.3 on the following
pages.

2.5 PCI Adapter Connectors
The following subsections describe the power and signal connectors on the PCI
adapter. Refer to Figure 2−5 for the location of these connectors on the adapter PCB.
2.5.1 Power Connector
The PCI adapter uses a 4−pin power
connector, illustrated at the right, to
supply the majority of power to the
PMC modules. This is a standard
disk drive power connector used in
PCs. (Molex 8981 Series Disk Drive
Connector Socket, Molex Model 15−
24−444.)
2.5.2 JTAG Connector
JP8, located next to the DIN connector on the right side of the board, is used
to connect the PCI bus “JTAG” signals to the PMC card. Normally, the
jumpers are not installed, so a JTAG connection to the PMC is not made. For
establishing a JTAG connection between the PCI edge fingers and the PMC
card, jumpers (not supplied) must be installed by the user. The pinout for
this 12−pin header is given in the following table.
