Zedboard FMC: External Clock

Hi all

I'm realy new to the Zedboard, but it looks very interesting.

An so I've a question: for a school-project I need an external clock in the PL (a teacher told me that this isn't realy complex). Unfortunately there isn't any SMA connector for an external clock (like it was at the spartan-3 boards). I read in this forum, that there are 2 possibile clock inputs on the FMC connector (FMC_CLK0_P / FMC-CLK0_N and FMC_CLK1_P / FMC-CLK1_N). So I could use them. Is there any existing fmc-board that I can use? I found several for ethernet, da and ad conversion, but nothing so simple.

And if there isn't one, what is the exactly connecter I've to use for a selfmade-board?

I hope you could help me...
thank you very much
best regards.

Hi Patrick,

One thing you could do is replace the PL clock chip at IC17 on ZedBoard with one of the desired frequency.

If you really need an external, off-the-board clock source, take a look at the XM-105 Debug FMC from Xilinx. It has two SMA connectors which can be used to connect a clock from a lab function generator into the FMC connector on a carrier board with SMA cable(s).
