1.5 Principle of Operation
The Model 52741 consists of one Pentek Model 71741 XMC module mounted on a Pen−
tek Model 5201 VPX carrier, assembled and tested as a single board. The Model 71741
XMC has a Pentek−supplied FPGA digital downconverter IP core. The Model 52741 is
ready to plug into a chassis with a single 3U VPX slot.
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 71741 XMC features a Xilinx Virtex−7 FPGA for signal interfaces and processing.
The FPGA is pre−configured with a digital down−converter IP core. This FPGA also
provides board interfaces including PCIe and XMC. Custom I/O connections are pro−
vided to the FPGA through the optional PMC P14 connector (Option 104). Custom
gigabit serial interfaces may be implemented through the optional XMC P16 connector
(Option 105).
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 data cap−
ture, as buffer memory when transferring data between board resources or to off−
board resources, or as a memory resource for custom FPGA applications.
The 71741 XMC can accept an external clock through front panel connectors. The 71741
is also equipped with an front panel sync bus that allows synchronizing A/D process−
ing on multiple modules.
The 5201 VPX carrier interface is configured in accordance with the VITA 65 OpenVPX
standard, which defines VPX Slot Profiles for various signal connections. The 5201
provides one x4 full−duplex serial connection between the 71741 XMC P15 connector
and the VPX−P1 connector, allowing high−speed data transfer to and from the XMC
module’s PCIe interface. For 71741 Option 105, the 5201 carrier provides one x8 (or two
x4) full−duplex, VITA 42.0 compliant, serial connection between the 71741 XMC P16
connector and the VPX−P1 connector. For 71741 Option 104 user I/O, the 5201 carrier
provides 24 differential pairs between the 71741 PMC P14 connector and the VPX−P2
connector.

2.3 Removing XMC Module from VPX Carrier
1) From the solder side of the VPX carrier (side opposite the 71741 XMC), unscrew the
four pan−head Phillips mounting screws, as identified below.
2) From the XMC module side, GENTLY, pull on the XMC card to disengage the card’s
connectors from the VPX carrier’s XMC connectors.
After jumper or switch changes, replace the XMC onto the VPX carrier as follows.
1) Position the 71741 XMC module’s front panel into the VPX carrier’s panel opening
from behind the VPX carrier slot panel, and align the 71741 XMC module so that the
connectors on the XMC card are aligned over the connectors on the VPX carrier.
2) GENTLY but firmly, press down on the areas of the XMC opposite the connectors to
fully seat the card’s connectors into the carrier. The connectors on the XMC should
connect smoothly with the corresponding connectors on the carrier.
3) From the solder side of the VPX carrier, secure the XMC to the carrier by screwing the
four pan−head Phillips mounting screws (those removed above) through the VPX
carrier into the XMC, as illustrated above.
