Application Diagrams

Figure 7 and Figure 8 show the application diagrams of a

Passive EMCA application using CCG2 devices. Figure 7 shows

the application using a single CCG2 device per cable present at

one of the two plugs, whereas Figure 8 shows the same with two

CCG2 devices per cable present at each plug. The VBUS signal,

the SuperSpeed lines, HighSpeed lines, and CC lines are

connected directly from one end to another.

The application diagram shown in Figure 7 requires a single

VCONN wire to run through the cable so that the CCG2 device

can be powered irrespective of which plug is connected to the

host (DFP). However, in the application diagram shown in

Figure 8, the VCONN signal does not run through the entire

cable, but only runs to the respective VCONN pin of the CCG2

device at each end of the plug. Also, only one CCG2 device is

powered at any given instance, depending on which one is

nearer to the DFP that supplies VCONN.
