The NI PXIe-8840 Quad-Core consists of the following logic blocks on two circuit card
assemblies (CCAs):
•
The
processor
is an Intel
®
Core
™
i7 5700EQ processor (6 MB Cache, 2.6 GHz). The
processor connects to the SO-DIMM block through the DDR3L interface supporting up
to 1600 MHz SO-DIMMs and the PCH through a x4 DMI2 (Direct Media Interface)
interface supporting up to 5 GT/s per lane.
•
The
SO-DIMM block
consists of one 64-bit DDR3L SDRAM socket that can hold up to
8 GB of memory.
•
The processor provides the DisplayPort interface that connects to display peripherals on
the NI PXIe-8840 Quad-Core, and the PCI Express interface to the PXI Express
backplane through a PCI Express switch.
•
The
Platform Controller Hub
(PCH) provides the USB, PCI Express x1, and LPC
interfaces that connect to the peripherals on the NI PXIe-8840 Quad-Core.
•
The
DisplayPort
block consists of two DisplayPort connectors.
•
The
USB
block consists of four Hi-Speed USB 2.0 connectors and two SuperSpeed USB
3.0 connectors.
•
The
GPIB
block contains the GPIB interface.
