preferable as it provides better trace loss
characteristic performance. See Note 1.
The following max length (delay) is derived
based on this characteristic. The length
(delay) constraint must be re-defined if loss
characteristic is changed.
6.9ps/mm assumption for Stripline,
5.9ps/mm for Microstrip.
