    Cyclone III

    Hello, the maximum the shift and update registers of the remote system upgrade for Cyclone III are clocked by the maximum frequency of 40-MHz user clock input (RU_CLK). There is no minimum
    frequency for RU_CLK.

    The CLKUSR pin allows a maximum frequency of 40 MHz (40 MHz DCLK) for Cyclone IV.

    Hope that helps.

    Thanks.
