Reportedly, each offers a unique set of software radio features in a full-length PCI Express (PCIe) board with the latest Gen 2 PCIe x16 interface. They incorporate up to two PMC/XMC modules, doubling the channel count of earlier models. The Model 7741 includes up to four 125-MHz, 14-bit ADCs and four 500-MHz, 16-bit DACs. 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. The Model 7742 includes up to eight 125-MHz, 14-bit ADCs, two up converters, and two 500-MHz, 16-bit DACs. The 7742 architecture also includes up to four Virtex-4 FPGAs. The Model 7750 includes up to eight 200-MHz, 16-bit ADCs, up to 3 MB of SDRAM, and up to four Virtex-5 FPGAs. The Model 7751 is a 512-channel digital down converter with up to eight 200-MHz ADCs and up to four Virtex-5 FPGAs. It features independent tuning for each DDC channel and decimation from 128 to 1,024 in steps of 64. The Model 7752 is a 64-channel down converter with up to eight 200-MHz, 16-bit ADCs and up to four Virtex-5 FPGAs. DDC decimation ranges from 16 to 8192 in steps of 8.
