With EMI, the issue usually isn't the application speed but the  
component speed. If your parts could work in a 500 MHz system, you  
often need to design for that speed, even if the actual system speed  
is much lower.

This can be a big problem in aerospace, where the speed on the spec  
sheet may be heavily "derated". The parts can surprise you with their  
true speed and the trouble that speed causes.
