PXIe-8840 Functional Description
The PXIe-8840 is a modular PC in a PXI Express 3U-size form factor. Figure 1-1 is a functional
block diagram of the PXIe-8840. Following the diagram is a description of each logic block
shown.
Figure 1-1. PXIe-8840 Block Diagram
The PXIe-8840 consists of the following logic blocks on two circuit card assemblies (CCAs):
•
The processor is an Intel ® Core ™ i5 4400E processor (3 MB Cache, 2.7 GHz). The
processor connects to the SO-DIMM block through the DDR3L interface supporting up to
1600 MHz SO-DIMMs, 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
PXIe-8840, and the PCI Express interface to the PXI Express backplane through a
PCI Express switch.
