Does anyone out there have the preferred configuration and equations for
controlling the impedance between a differential pair of traces that are
sandwiched between two power planes on epoxy-glass?
Also, does it matter if one of the power planes is ground and the other
"hot", or will the inevitable in-circuit capacitance between them ensure
a common ac reference at typical transmission line frequencies?
Thanks,
