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.
2
Opposing directional 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.
