STRATIX family comparison (novice).

hi,

I still have some question, someone could enlighten me please?

It is written in Stratix 3 and Stratix 4 Handbook that:

--- Quote Start ---

general-purpose i/o standards such as 3.3,

2.5, 1.8, and 1.5 lvttl/lvcmos are capable of typical 167 mhz and 1.2 lvcmos at

100mhz interfacing frequency with 10pf load.

--- Quote End ---

but I didn't find the equivalent information for Stratix 2.

I want this information in order to compare 3.3v lvttl pins data rates for the different FPGAs of the STRATIX family.

Thank you,

Amin
