Virtex5 BUFR min frequency

Hi all,

I've a question about BUFR primitives. I read in the datasheet that BUFR can distribute their output clock on clock regions, and have the availability to divide the input clock frequency by an integer (between 1 and 8). But, after reading AC specifications, I could not found the minimum frequency of the BUFR output clock ( when divider is equal to 8).

So if anyone could help me ?

Thanks by advance,

Best regards, Michel.
