HD3SS3212: HD3SS3212 Super Speed Signal Routing / MUX control Logic

Part Number: HD3SS3212
Other Parts Discussed in Thread: TUSB321,

Hello,

We are designing a product that has Type-C port, we used TI solutions for CC controller (TUSB321) and MUX (HD3SS3212RKS).

Can you please help us clarify few doubts to implement the straight net flow for the USB3 super speed signals?

Question no 1

In the highlighted schematics we have swapped USB3 SS Pairs and polarity as well (Green color net).

Can you please confirm the way we connected is right? (Based on the USB3 polarity inversion support on the physical layer)

Question No 2

For implementing the above mentioned changes, do we need to swap CC 1& 2 signals across the (TUSB321) controller as per the datasheet?

We have directly connected the CC pins to TUSB321 controller and the DIR_MUX net is connected to the MUX with the pull-up resistor.

 Thanks

Antony
