Clock Pins on Cyclone IV?

Does anyone know the pin of 50Mhz clock on Cyclone IV GX? I searched every where but couldn't find it. I need it as an input clock for my project. :oops:

    Look at the data sheet of the device you are using and chose one of the CLK or DPCLK inputs!

    Or check the schematics of whatever board it's on.

    If you are talking about a Cyclone IV development kit and not a Cyclone IV fpga, you will have to tell which kit you are talking about.

    Or just have a look at the schematic in the kit installed files, you'll find the pin the oscillator is connected to.
