The scenario
A USB-C dock routes CC and PD signals from the input connector to downstream ports through a switch matrix while a VBUS load switch handles power delivery.
What is in this drawing
Read the decisions behind it.
01
Separate CC and PD controller blocks model the signal negotiation path before the switch matrix.
02
VBUS load switch is placed parallel to the CC/PD switch matrix to handle power routing.
03
Boundary in/out ports mark the external USB-C source and downstream sink.
Reuse for USB-C dock, hub, or dongle wiring diagrams where CC/PD switching and VBUS power paths must be documented.
