TPS65987D: USB type-C Displayport + USB 3.0, and Displayport++ (HDMI) mode.

Part Number: TPS65987D

Hey Team,

I had a couple questions regarding what sort of signals can be passed over USB type-C cables regarding USB 3.0, DisplayPort, and Displayport++.

1. My understanding is you can have dedicated USB 2.0 and USB 3.0 signals since the USB 3.0 signals pass over the TX/RX lines - can you have 2 separate USB 3.0 signals passed over a single type-C cable? (such that you do not need a hub on the receive end?)

2. Can you do the same with DisplayPort + 2x USB 3.0 - my understanding is that you can do DisplayPort + 1 USB 3.0 signal.

3. What type-C line does DisplayPort++ run over, does DP++ work over type-C at all? (I was thinking this might run over the SBU lines, but it was not clear)

Thank you for your help!!

best regards,

Hi Saqib,

Sorry for the delay in getting back to you:

1. The redundant super speed lines are for handling the cable flip and not for passing double the data. If you are interested in increased data throughput, you should consider implementing a thunderbolt system as this would allow for up to 40GB/s.

2. DP alternate mode would not support this as it is not one of the DP Pin assignments.

3. DP ++ would also go over the SS TX/RX lines on the Type-C cable.

If this answers your question, PLEASE select This resolved my issue

Thank you,

Eric
