A discontinuity of channel severely affects a signal quality on the high speed systems. The more the routing of signal lines is complicated, the reference changing happens frequently. This reference crossing brings about the sudden change of signal line impedance and the reflection from this fact distorts the transfer signal. In this paper, the reference crossing effects are analyzed from the circuit modeling.
