Lo scenario
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.
Cosa contiene questo disegno
Leggi le decisioni che ne stanno alla base.
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.
