NI 5762 Component-Level Intellectual Property (CLIP)
The LabVIEW FPGA Module includes a feature for HDL IP integration called CLIP. NI FlexRIO
devices support two types of CLIP: user-defined and socketed.
•User-defined CLIP allows users to insert HDL IP into an FPGA target, enabling VHDL code to
communicate directly with an FPGA VI.
•Socketed CLIP provides the same IP integration functionality of the user-defined CLIP, but it also
allows the CLIP to communicate directly with circuitry external to the FPGA. Adapter module
socketed CLIP allows your IP to communicate directly with both the FPGA VI and the external
adapter module connector interface.
Figure 4 shows the relationship between an FPGA VI and CLIP.

The NI 5762 ships with socketed CLIP items that are used to add module I/O to the LabVIEW project.
The NI 5762 ships with the following CLIP items:
•NI 5762 Multiple Sample CLIP—This CLIP generates two samples per clock cycle at a clock rate
that is half the sample rate. The default sample rate is 250 MHz, which sets the default clock rate
for this CLIP at 125 MHz. You can set a lower sample rate by using an external Sample clock. This
CLIP provides access to two analog input channels, eight DIO lines, four PFI lines, and an input
clock selector that can be configured to use one of the following settings:
– Internal Sample clock
– Internal Sample clock locked to an external Reference clock through Sync Clock
(IoModSyncClk)
– Internal Sample clock locked to an external Reference clock through the CLK IN connector
– External Sample clock through the CLK IN connector
This CLIP also contains an engine to program the clock chip and ADCs, either through predetermined
settings for an easier instrument setup or through a raw SPI address and data signals for a more advanced
setup. Additionally, this CLIP provides an I2C interface to access a user EEPROM and a temperature
sensor. In the LabVIEW FPGA Module, each analog signal uses a signed I16 data type. The DIO signals
are grouped into two ports of four signals each and are accessed using a U8 data type and Boolean write
enable signal. The four PFI signals are accessed individually using Boolean controls.
The NI 5762 Multiple Sample CLIP is the default CLIP.
•NI 5762 Single Sample CLIP—This CLIP generates one sample per clock cycle at a default
sample rate of 250 MHz. You can set a lower sample rate by using an external Sample clock. This
CLIP provides access to two analog input channels, eight digital input/output lines, four PFI lines,
and an input clock selector that can be configured to use one of the following settings:
– Internal Sample clock
– Internal Sample clock locked to an external Reference clock through Sync Clock
(IoModSyncClk)
– Internal Sample clock locked to an external Reference clock through the CLK IN connector
– External Sample clock through the CLK IN connector
This CLIP also contains an engine to program the clock chip and ADCs, either through predetermined
settings for an easier instrument setup or through a raw SPI address and data signals for a more advanced
setup. Additionally, this CLIP provides an I2C interface to access a user EEPROM and a temperature
sensor. The DIO signals are grouped into two ports of four signals each and are accessed using a U8 data
type and Boolean write enable signal. The four PFI signals are accessed individually using Boolean
controls.
Refer to the NI FlexRIO Help for more information about NI FlexRIO CLIP items, configuring the
NI 5762 with a socketed CLIP, and a list of available socketed CLIP signals.

and CLK IN connectors on the NI 5762 front panel.
Use any HDMI cable with the two provided cable ferrites to connect to the digital I/O and PFI signals
on the AUX I/O connector. Refer to the Appendix: Installing EMI Controls section for more information
about attaching cable ferrites.
For more information about connecting I/O signals on your device, refer to the Specifications section of
this document.
Clocking
The NI 5762 clocks control the sample rate and other timing functions on the device. Table 4 contains
information about the possible NI 5762 clock resources. For more clocking information, refer to the
CLK IN section of the specifications.
Using Your NI 5762R with a LabVIEW FPGA Example VI
Note You must install the software before running this example. Refer to the NI FlexRIO FPGA
Module Installation Guide and Specifications for more information about installing your software.
The NI FlexRIO Adapter Module Support software includes a variety of example projects to help get
you started creating your LabVIEW FPGA application. This section explains how to use an existing
LabVIEW FPGA example project to generate and acquire samples with the NI 5762R. This example
requires at least one SMA cable for connecting signals to your NI 5762R.
Note The examples available for your device are dependent on the version of the software and driver
you are using. For more information about which software versions are compatible with your device,
visit ni.com/info and enter rdsoftwareversion as the Info Code.
Each NI 5762R example project includes the following components:
• A LabVIEW FPGA VI that can be compiled and run on the FPGA embedded in the hardware. This
VI is referred to as the FPGA Target VI.
• A VI that runs on Windows that interacts with the LabVIEW FPGA VI. This VI is referred to as
the Host VI.
