情境
A dock test tool must verify routing between the USB-C receptacle's 24 pins and switched test points for CC, sideband, high-speed, and power rails.

看懂背後的決策。
01
Split the receptacle into independent CC, SBU, USB 3.2, VBUS, and GND signal paths
02
Use a dedicated high-speed mux to switch USB 3.2/DP Alt lanes to SMA test points
03
Keep dock controller as a separate controller block driving mux select lines
Use this pattern when documenting or building a USB-C dock test fixture that needs to map receptacle pins to configurable test points.
