New L-Band RF Tuner Offers Improved Bandwidth for Satcom and Comm Apps


Model 71791 is a member of the Onyx® family of high performance XMC modules based on the Xilinx Virtex-7 . It is suitable for connection directly to an L-band signal for SATCOM and communications systems. Its built-in data capture features offer an ideal turnkey solution as well as a platform for developing and deploying custom FPGA processing IP. It includes an L-Band RF tuner, two A/Ds and four banks of memory. In addition to supporting PCI Express Gen. 3 as a native interface, the Model 71791 includes general purpose and gigabit serial connectors for application-specific I/O .

The Pentek Onyx Architecture features a Virtex-7 FPGA. All of the board’s data and control paths are accessible by the FPGA, to suport factory-installed functions including , control, channel selection, data packing, gating, triggering and memory control. The Onyx Architecture organizes the FPGA as a container for data processing applications where each function exists as an intellectual property (IP) module. The 71791 factory-installed functions include two acquisition IP modules, four DDR3 memory controllers, two digital down converters, an RF tuner controller, a clock and synchronization generator, a test signal generator, and a Gen 3 PCIe interface. Thus, the 71791 can operate as a complete turnkey solution with no need to develop FPGA IP.
