Chris,
While you can infer some Tr from the harmonics, you can't infer the Data
rate or Clock frequency. But usually, the SI danger is in the edge.

Scott,

What are the harmonics of the signal spectrum that need to be in the 5-10GHz
range in order for an additional C to take effec? When that question is
answered, the fundamental frequency and associated Tr may be implied as
well.
