Stratix V "CLKUSR"-Pin

Hi !

Maybe you can help me to get it right :)

I found this in stratix 5 handbook:

"The CLKUSR pin provides you with the flexibility to synchronize initialization of multiple devices or to

delay initialization."

So i can supply the "CLKUSR"-pin with a external clk-signal and this clk will be used to synchronize both fpga's?

Where can i get more information about the "CLKUSR"-pin?? (working through some .pdf's but without finding much information at the moment)

thanks in advance

    Yes, you can synchronize initialization of multiple FPGAs, which means that they will start working simultaneously.

    Additional info (albeit scarce) is provided by pin connection guidelines (http://www.altera.com/literature/dp/stratix-v/pcg-01011.pdf) PDF.
