Reconfigurable FPGA

PXIe-5764 modules are available with multiple FPGA options. The following table lists the FPGA specifications for the PXIe-5764 FPGA options.

Note The Reconfigurable FPGA Options table depicts the total number of FPGA resources available on the part. The number of resources available to the user is slightly lower, as some FPGA resources are consumed by board-interfacing IP for PCI Express, device configuration, and various board I/O. For more information, contact NI support.

Note For FPGA designs using the majority of KU040 or KU060 FPGA resources while running at clock rates over 150 MHz, the module may require more power than is available. If the module attempts to draw more than allowed per its specification, the module protects itself and reverts to a default FPGA personality. Refer to the getting started guide for your module or contact NI support for more information.

NI-TClk

You can use the NI-TClk synchronization method and the NI-TClk driver to align the Sample Clocks on any number of supported devices in one or more chassis. For more information about TClk synchronization, refer to the NI-TClk Synchronization Help within the FlexRIO Help. For other configurations, including multichassis systems, contact NI Technical Support at ni.com/support.

Intermodule Synchronization Using NI-TClk for Identical Modules

Synchronization specifications are valid under the following conditions:

All modules are installed in one PXI Express chassis.
The NI-TClk driver is used to align the Sample Clocks of each module.
All parameters are set to identical values for each module.
Modules are synchronized without using an external Sample Clock.

Note Although you can use NI-TClk to synchronize non-identical modules, these specifications apply only to synchronizing identical modules.
