I bought this board (I'm waiting to receive it) meantime I'm looking the electrical schematic and I've noticed about the clock frequency that IC4 (sheet 3/7 Rev B.1) should be a 100 MHz clock, also I can see a USB_12MHZ line that came into the GCLK line through a resistor R80, I kindly ask you if U4 is the predefinited source of clock of the FPGA and then R80 is not mounted into the board because I need to setup a design able to operate with a 50 MHz clock and if the supplied clock generator supplied with the board is 100 MHz I'm very happy.
Could you please let me know more about this point?

Dear All,
I bought this board (I'm waiting to receive it) meantime I'm looking the electrical schematic and I've noticed about the clock frequency that IC4 (sheet 3/7 Rev B.1) should be a 100 MHz clock, also I can see a USB_12MHZ line that came into the GCLK line through a resistor R80, I kindly ask you if U4 is the predefinited source of clock of the FPGA and then R80 is not mounted into the board because I need to setup a design able to operate with a 50 MHz clock and if the supplied clock generator supplied with the board is 100 MHz I'm very happy.
Could you please let me know more about this point?
Thanks!
