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.
