Functional Overview

    Last Modified: February 23, 2017

    The PXIe-8840 is a modular PC in a PXI Express 3U-size form factor. The following figure is a functional block diagram of the PXIe-8840. Following the diagram is a description of each logic block shown.

    Figure 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 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 PXIe-8840, 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 PXIe-8840.
    • 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.
    • The ExpressCard/34 slot accommodates an ExpressCard/34 module.
    • The Ethernet Port 1 block consists of an Intel® I217-LM Gigabit Ethernet Connection.
    • The Ethernet Port 2 block consists of an Intel® I210-IT Gigabit Ethernet Connection.
    • The UART block connects to one serial port.
    • The SMB Front Panel Trigger provides a routable connection of the PXI triggers to/from the SMB on the front panel.
    • The Watchdog block consists of a watchdog timer that can reset the controller or generate triggers.
    • The PXI Express Connectors connect the PXIe-8840 to the PXI Express/CompactPCI Express backplane.
