7811 Pentek Quad Serial FPDP PCIe Interface with Virtex-6 FPGA

The Pentek 7811 Series Quad Serial FPDP PCIe Interfaces with Virtex-6 FPGA is a member of the Cobalt family of high performance XMC modules based on the Xilinx Virtex-6 FPGA. A multichannel, gigabit serial interface, it is ideal for interfacing to Serial FPDP data converter boards or as a chassis-to-chassis data link.

The 7811 is fully compatible with the VITA 17.1 Serial FPDP specification. Its built-in data transfer features make it a complete turnkey solution. For users who require application-specific functions, the 7811 serves as a flexible platform for developing and deploying custom FPGA processing IP.

The Pentek Cobalt Architecture features a Virtex-6 FPGA. All of the board's data and control paths are accessible by the FPGA, enabling factory-installed functions including data transfer and control. The Cobalt Architecture organizes the FPGA as a container for data processing applications where each function exists as an intellectual property (IP) module.

IP modules for data routing and flow control, CRC support, advanced DMA engines, and a PCIe interface complete the factory-installed functions and enable the 7811 to operate as a complete turnkey solution without the need to develop any FPGA IP.

For applications that require specialized function, users can install their own custom IP for data processing. Pentek GateFlow FPGA Design Kits include all of the factory-installed modules as documented source code. Developers can integrate their own IP with the Pentek factory-installed functions or use the GateFlow kit to completely replace the Pentek IP with their own.

The Virtex-6 FPGA can be populated with two different FPGAs to match the specific requirements of the processing task. Supported FPGAs include: LX130T, LX240T or SX315T. The SX315T part features 1,344 DSP48E slices and is ideal for modulation/demodulation, encoding/decoding, encryption/ decryption, and channelization of the signals between transmission and reception.

For applications not requiring large DSP resources, the cost-effective LX130T FPGA can be installed.

The 7811 is fully compatible with the VITA 17.1 Serial FPDP specification. With the capability to support 1.0625, 2.125, 2.5, 3.125, and 4.25 Gbaud link rates and the option for multi-mode and single-mode optical interfaces or copper interfaces the board can work in virtually any system. Programmable modes include: flow control in both receive and transmit directions, CRC support, and copy/loop modes.

The 7811 includes an industry-standard interface fully compliant with PCI Express bus specifications. Supporting PCIe links up to x8, the interface includes eight DMA controllers. Each of the four Serial FPDP channels includes dedicated DMA engines for transmit and receive for efficient transfers to and from the board.
