Output FPGA Clock

[bchang32]

Hello,

I am trying to output my FPGA clock from my timed sequence, but it appears the FPGA clock datatype cant go into anything. Is there any way to output the FPGA Clock to a node/Port so i cant verify the signal. I have a 6584 to output it to.

Any info would be appreciated

What FPGA is generating this clock? You can't feed that clock item into anything but a SCTL but some modules can be configured to just output the clock on specific pins.

Also what exactly is the end goal here? I'm trying to understand what you are looking to accomplish by trying to verify a clock through a digital input.

our FlexRIO 7972 is generating this clock.

How would I go about outputting the clock on a single cycle timed loop?

We want to use it to ensure we're getting the right output (so to verify our signal).

What adapter module is connected to that card?

NI 6584

The 6584 has example projects which export the clock through the BNC connector on the front end. A few examples show this including "NI 6584 Finite Generation and Exported Clock (Full Duplex)".

Essentially all you do is write TRUE to the Clock_Out_Enable CLIP item. What clock is output is configured in the properties of the IO Module project item under the "Clock Selections" page.

Yes but isnt the Clock out limited to 16MHz? I want to have a pin i.e. TX7 output at 200 MHz. I got it to output at 100MHz, but if I could get it to export the clock essentially at 200MHz, that would be perfect.
