With the launch of its Quartz model 5550 RFSoC board,Pentekstakes out a leadership position in the defense/aerospace sector’s adoption of the Sensor Open System Architecture (SOSA) Technical Standard and the reference architecture it defines. To that end, the board implements connector technology that enables a major goal of the SOSA reference architecture—backplane-only I/O. It incorporates the ANSI/VITA 67.3D VPX backplane interconnect standard for both coaxial RF and optical I/O. In addition, the Model 5550 includes a 40-GbE interface and a shelf-management subsystem that are also required by the SOSA reference architecture.
The 3U OpenVPX board, equipped with PCI Express Gen 3 capabilities, comprises an eight-channel analog-to-digital converter (ADC) and digital-to-analog converter (DAC) and is based on the Xilinx Zynq UltraScale+ RFSoC FPGA. It’s aimed squarely at applications in communications, electro-optics, electronic warfare, and radar and signals intelligence.
Pentek的硬件和软件模块化方法可以快速适应新的和不断变化的客户需求。5550模型使用型号的6001石英型Express模块，该模块包含RFSOC FPGA以及在载波模块上实现的所有需要的支撑电路，该电路专门与SOSA参考体系结构的技术标准相符。这样可以在可用时轻松升级到第三代RFSOC模块。
The Model 5550 is pre-loaded with a suite of Pentek IP modules to provide data capture and processing solutions for many common applications. Modules include direct-memory-access (DMA) engines, DDR4 memory controller, test signal and metadata generators, data packing, and flow control. The board also comes pre-installed with IP for triggered waveform and radar chirp generation, triggered radar-range gate selection, wideband real-time transient capture, flexible multimode data acquisition, and extended decimation. For many applications, the Model 5550 can be used out-of-the-box with these built-in functions, requiring no FPGA development.
The front end accepts analog IF or RF inputs on eight coax connectors located within a VITA 67.3D backplane connector. After balun coupling to the RFSoC, the analog signals are routed to eight 4-GS/s, 12-bit ADCs. Each converter has built-in digital downconverters with programmable 1x, 2x, 4x, and 8x decimation plus independent tuning. The ADC digital outputs are delivered into the RFSoC programmable logic and processor system for signal processing, data capture, or routing to other resources. A stage of IP-based decimation provides another 16x stage of data reduction, ideal for applications that need to stream data from all eight ADCs.
八个4-GS/s，14位DACS将Balun耦合的模拟输出传递到第二Vita 67.3d同轴背板连接器。为时钟和计时信号提供了另外四个同轴轴向背板连接。
The Model 5550 also uses the VITA-67.3D backplane connector for eight 28-Gb/s duplex optical lanes to the backplane. With two built-in 100 GigE UDP interfaces or a user-installed serial protocol in the RFSoC, the VITA-67.3D backplane interface enables gigabit communications independent of the PCIe interface.
Navigating IP
For cases in which IP development proves necessary, Pentek’s Navigator Design Suite streamlines the process. The suite includes the Navigator FDK (FPGA Design Kit) for custom IP and Navigator BSP (Board Support Package) for creating host software applications. The Navigator FDK includes the board’s entire FPGA design as a block diagram that can be edited in Xilinx's Vivado tool suite. All source code and complete documentation is included. Developers can integrate their IP along with the factory-installed functions or use the Navigator kit to replace the IP with their own. The Navigator FDK Library is AXI-4 compliant, providing a well-defined interface for developing custom IP or integrating IP from other sources.
The Navigator BSP supports Xilinx’s PetaLinux on the Arm processors. Users can work efficiently using high-level API functions, or they can gain full access to the underlying libraries including source code. Pentek provides numerous examples to assist in the development of new applications.
8257 Model是一个现成的石英开发平台，是一种低成本3U VPX机箱，非常适合在PenTek的5550型Quartz RFSOC板上开发应用程序。底盘提供电源和冷却以匹配5550的5550，允许访问所有必需的接口和型号5901后过渡模块。8257可以使用可选的Real-Panel双MPO光学连接器配置，以支持5550的双100-GBE接口和同轴RF连接器。
5550董事会专为气冷，传导冷却和坚固的操作环境而设计，起价为38,745美元。可以使用光学接口，GPS支持和内存的选项。交货从2020年第三季度开始。导航器BSP和Navigator FDK的价格分别为$ 2,500和3,500美元。两者都包括免费的终身支持。
