The National Instruments PXI-7951R and PXI-7851R Virtex-5 LX30 FPGA modules are powerful additions to any PXI (PXI Express) system, offering high-performance FPGA fabric for custom data acquisition, control, and processing applications. These modules are part number 780339-01.

The PXI-7951R FPGA module features a Virtex-5 LX300 FPGA device, providing 1,320,000 logic cells, 3,840 DSP slices, and 132 Megabits of SRAM. With a maximum clock frequency of 100 MHz, this module delivers ample processing power for complex applications. The PXI-7951R also includes two 148-pin FPGA board-to-board connectors, allowing for flexible interfacing with other PXI modules.

The PXI-7851R Virtex-5 LX30 FPGA module is similar to the PXI-7951R, but it comes with an additional onboard ADC (Analog-to-Digital Converter) subsystem. This 14-bit, 50 Msps (Mega Samples per Second) ADC features eight channels and offers high-speed data conversion capabilities. The PXI-7851R module is perfect for applications that require both FPGA processing and high-speed data acquisition.

Both modules offer several interfaces, including one PXI Express backplane connection, one 100BASE-TX Ethernet port, and one USB 2.0 Type B host interface. They also include a variety of onboard digital I/O lines, including high-speed differential I/O and configurable digital I/O.

The PXI-7951R and PXI-7851R modules are designed for use in rugged industrial environments, with operating temperatures ranging from -20 C to 65 C. They offer robust EMI/EMC protection, ensuring reliable operation even in environments with high electromagnetic interference.

In summary, the National Instruments PXI-7951R and PXI-7851R Virtex-5 LX30 FPGA modules offer high-performance FPGA processing and flexible interfacing capabilities for PXI systems. The PXI-7951R provides a powerful FPGA fabric, while the PXI-7851R adds a high-speed ADC subsystem for data acquisition applications. Both modules are designed for rugged industrial environments and offer multiple interfaces for flexibility and ease of use.

The National Instruments (NI) PXI-7951R and PXI-7851R are both FPGA (Field Programmable Gate Array) modules from National Instruments, with the main difference being that the PXI-7951R includes the Virtex-5 LX30 FPGA chip, while the PXI-7851R uses a smaller FPGA chip. Here are some pros and cons of each, followed by a conclusion and recommendation.

1. Lower cost: The PXI-7851R is generally less expensive than the PXI-7951R due to its smaller FPGA chip.

2. Smaller form factor: The size of the PXI-7851R module is smaller than that of the PXI-7951R, making it a better choice for applications with limited space.

3. Lower power consumption: The smaller FPGA chip on the PXI-7851R consumes less power than the Virtex-5 LX30 chip on the PXI-7951R.

1. Limited FPGA resources: The smaller FPGA chip on the PXI-7851R offers fewer resources than the Virtex-5 LX30 chip on the PXI-7951R, which may limit its capabilities for more complex applications.

2. Slower processing speed: The smaller FPGA chip on the PXI-7851R also means slower processing speeds than the PXI-7951R.

1. More FPGA resources: The larger Virtex-5 LX30 FPGA chip on the PXI-7951R offers more resources, making it a better choice for more complex applications.

2. Faster processing speed: The larger FPGA chip on the PXI-7951R also means faster processing speeds than the PXI-7851R.

1. Higher cost: The PXI-7951R is generally more expensive than the PXI-7851R due to its larger FPGA chip.

2. Larger form factor: The size of the PXI-7951R module is larger than that of the PXI-7851R, which may not be ideal for applications with limited space.

3. Higher power consumption: The larger FPGA chip on the PXI-7951R consumes more power than the smaller FPGA chip on the PXI-7851R.

Both the PXI-7851R and PXI-7951R have their strengths and weaknesses. The PXI-7851R is a better choice for applications with limited space and budget requirements, or for simpler applications that don't require a lot of FPGA resources or processing power. On the other hand, the PXI-7951R is a better choice for more complex applications that require more FPGA resources or faster processing speeds, even if it comes at a higher cost and greater power consumption. In summary, the choice between the two depends on the specific requirements of the application.

If your application requires a lot of FPGA resources or fast processing speeds, and you have the budget and power supply to accommodate the larger module, I would recommend the PXI-7951R. However, if your application is simpler and doesn't require as many FPGA resources or processing power, and you need to keep costs and power consumption low, the PXI-7851R may be the better choice for you.
