Codirectional channel matching is the absolute value of the difference in propagation delays between any two channels with inputs on the same side of the isolation
barrier. Opposing-direction channel matching is the absolute value of the difference in propagation delays between any two channels with inputs on opposing sides
of the isolation barrier.
