Other Parts Discussed in Thread: TPS65987D

Hi ti Team， 

Further review to the type C Block diagram, I have a new comment please review if it is possible to implement.

1,USB audio is a default setting for the system, play back for 192K/96K/88.2K/48K/44.1K sampling USB audio signal, since it is an important feature of the product, I would like to exchange USB audio chip D+,D- signal with the USB type C controller as illustrated by below photo, the USB audio D+,D- only need to go through an USB switch but not two switchs to maintain high quality RF signal .is there any issues for D+,D- signal deom USB type C connector to USB controller chip via two switchs?

2,Need to support BC1.2    please confirm.

    Hello,

    If you are not implementing TBT3 functionality, you will need to use the TPS65987D and not the TPS65987DDJ. These devices are identical from a hardware perspective, just the internal firmware is different. The TPS65987DDJ is intended for applications following a TBT reference design while the TPS65987D is intended for everything else. 

    As far as BC1.2 and Type-C enablement, the TPS65987D will meet both of these requirements
