Hi all,

This may be a repetitive question but, is there a rule of thumb or a good
way to calculate the input and output impedance of an IC? I know there are
measurement techniques, but how can you get a proper trace impedance if this
info is not know from the start? I appreciate the help.

Toby, CID
