Interface 1.2V to TTL

The new Spartan 3 chips are nice $12.5 for 1 mega-gates. However, my problem is, how do we interface to these monsters? They are 1.2V and most anything else is 3.3V Can they drive a 3.3V "TTL" input? Any comments and suggestions appreciated?

Yes. You have to provide a separate supply for the outputs, which can be set to many different output standards.

Yes, they can drive LVTTL, but if you are planning to use Spartan-3 with PCI, have a look at this application note.
