3.4 CCG2 Two-Chip EMCA Application (One Chip Powered)
The CY4502 board can operate in the two-chip EMCA application, with only one of the two CCG2 controllers powered, as
shown in
Figure 3-7 . Follow these steps to configure the board for this mode (depicted in Figure 3-6 ):
1. Short pins 1 and 2 of jumper J6.
2. Short pins 1 and 2 of jumper J7.
3. Leave jumpers J8 and J13 open.
4. Leave jumper J5 open.
Follow instructions in section 3.6 to test the CY4502 board.

This EMCA solution contains two CCG2 controllers, one in each plug. In this solution, the VCONN signal does not run
through the cable. Only one CCG2 is powered at a time depending on which is nearer to the DFP that supplies VCONN.
The powered CCG2 responds to SOP’ packets only. For more details on this application, refer to
AN95615 .
