Question regarding PLD speeds.

[GUARBorg]

I'm sourcing a replacement GAL22V10B-25LP, but all I can find is GAL22V10B-15LP. The difference in the part code is 15 & 25. All that represents is the speed of the PLD in ns.

So my question is: Will replacing a 25ns PLD with a 15ns PLD have negative effects?

Yes, but not a great one. Genius G540

Yes, I have known good PLD I'm reading from to program into any replacements.

Do you have a suggestion for a good programmer? Using the G540 again is reminding me just how bad it really is. I may just post this question as a new thread if using the search feature doesn't turn up anything.
