This EMCA solution contains two CCG2 controllers, one on each plug, and the power (VDDD) of both the CCG2 devices is
wired across the cable (but not straight through to the other end of the plug). Even in this solution, the wiring is done such
that the cable is reversible. The VCONN signal from one cable plug goes to the VCONN1 pin of the CCG2 at that end and
also to the VCONN2
/ VDDD pin of the CCG2 at the other end of the cable. The same applies to the VCONN signal
coming from the other end of the cable. Both CCG2 devices will be powered: one through VCONN1 and the other through
VCONN2
/ VDDD. The CCG2 powered through VCONN1
responds to SOP’ packets and the other CCG2 responds to
SOP”.
This configuration option of the
DVK helps in evaluating firmware support for SOP”. In production, this configuration will
typically only be used in active cables. When the active cable requires independent management or signal conditioning at
each end of the cable, separate
USB PD controllers responding to USB PD structured VDMs (SOP’ and SOP” packets)
must be located in each plug. For more details on this application, refer to AN95615 - Designing USB 3.1 Type-C Cables
