Codirectional channel matchi ng is the absol ute value of the difference in propa gation delays betwee n any two c hannels with i nputs on the same side of the isolati on barrier. Opposing-directional channel matching is the abs olute val ue of the differe nce in propagati on delays betwee n any two c hannels wit h inputs on opposi ng sides of the is olation barrier.
|CM| is the maximum common-mode voltage slew rate that can be sustained while maintaining V
rising and falling common-mode voltage edges.
