Hi all,
I was wondering if anyone out there knows of a spec that discusses any
standard on tuning differential pairs?  We have a few schools of
thought, make up the length at the source pin, or add serpentine to the
shorter line.  We have also added length to every segment, but on tight
boards, this really isn't a viable option.  
It would be really helpful to be able to point to a study that show some
data on how this would affect the impedance.
Thanks,
Carol
