Pentek Cobalt Analog I/O with Virtex-6 FPGA
Pentek's Virtex-6 FPGA based family of XMC, PCIe & cPCI cards (for data acquisition, software radio and digital signal processing), provide
a range of analog front end features delivering excellent dynamic range and input/output bandwidth for signal intelligence, radar and beamforming
The memory architecture is modular, giving users a choice of memory types. Applications requiring deep, fast memory can choose the DDR3. Other
applications requiring simultaneous read/write access can choose QDRII+. For ultimate flexibility, a mixture of both memory types is available.
PCI Express (Gen 2.0) is used as the primary control and data streaming interface. With lane widths upto x8, data can be moved on and off the
board at rates up to 2GB/sec (full duplex). Such rates are invaluable for moving the full bandwidth, multi-channel data required in many
applications. With dual XMC connectors, the module can support additional protocols, like Aurora, or Serial RapidIO on the second connector. This
is ideal for applications that require high-speed board-to-board communication paths while still maintaining the PCIe interface.
As with previous Pentek products the modules feature high-speed ADC/DAC channels linked to FPGAs which can implement Digital Down Conversion (DDC).
Customers who want an off-the-shelf solution can buy the product with a DDC core pre-loaded into the FPGA. Alternatively, customers can write their
own FPGA code and download it to the board using the Gateflow FPGA Design Kit.
The XMC (Model 716XX) card is used as the base module and is listed in the table below. PCIe, cPCI and AMC form factors are supported through the
use of an appropriate Pentek carrier card.
