The Pentek 7700 series of software defined radio modules feature the PCI Express (PCIe) form factor with advanced connectivity options. The Pentek 7700 series consist of the 7741, 7742, 7750, 7751, and 7752 models. Each offers a unique set of software radio features in a full-length PCI Express (PCIe) board with the very latest Gen 2 PCIe x16 interface. Each of the five software radio boards offers specific resources including channel count, bandwidth, FPGA population and more.
The 7700 full-length PCIe boards features up to two PMC/XMC modules, all within a single PCIe envelope. This doubles the channel count of earlier models, and delivers a lot of performance in a very small volume. Customers can utilize the PCIe interface for motherboard connections and XMC interfaces for gigabit links between modules and other boards. This flexibility allows users to build high-speed multi-board PC systems at relatively low costs.
Another feature common to all the boards in the Pentek 7700 family is the 4-pin disk drive power connector to ensure that the boards receive ample power from the host computer or server. This augments the power supplied through the PCIe backplane connector.
The Models 7741, 7742, and 7750 have user-configurable FPGAs. Because the Model 7751 and 7752 have preinstalled FPGA digital downconverter IP cores, they do not require user programmability.
Pentek 7700 Series SDR Boards
This SDR includes up to four 125 MHz, 14-bit A/Ds and four 500 MHz 16-bit D/As. It features one or two TI/Graychip GC4016 quad digital down converters with output bandwidths up to 10 MHz, and one or two digital up converters that accept baseband real or complex data streams with signal bandwidths up to 40 MHz. One or two Xilinx XC2VP50 Virtex-II Pro FPGAs serve as control and status engines with data and programming interfaces to each of the on-board resources, including the A/D converters, digital down converters, digital up converters and D/A converters.
The module includes up to eight 125 MHz, 14-bit A/Ds, two up converters and two 500 MHz 16-bit D/As. The 7742 architecture also includes up to four Virtex-4 FPGAs.
This model includes up to eight 200 MHz, 16-bit A/Ds, up to 3 MB of SDRAM, and up to four Virtex-5 FPGAs.
This board is a 512-channel digital downconverter with up to eight 200 MHz A/Ds and up to four Virtex-5 FPGAs. This represents a tremendous amount of processing power in a single PCIe slot. It features independent tuning for each DDC channel, and decimation from 128 to 1024 in steps of 64.
This SDR is a 64-channel downconverter with up to eight 200 MHz, 16-bit A/Ds and up to four Virtex-5 FPGAs. Each group of four A/Ds is supported by a high-performance 32-channel digital downconverter. DDC decimation ranges from 16 to 8192 in steps of 8.
