HD3SS2522: HD3SS2522 schematic trace define issue

Kevin Peng

Part Number: HD3SS2522

Hi Sir

I am confused for HD3SS2522 schematic, EVM board with datasheet I / O signal trace is somewhat different.
Please refer to below.
1. As shown in datasheet suggested schematic signal trace, pin 2 & 3 and 5 & 6 with pin 44 & 43 trace opposite?

2. As shown in EVB suggested schematic signal trace, pin 2 & 3 and 5 & 6 with pin 44 & 43 trace same the opposite?

3. As shown in datasheet Layout trace is different from with above,

4. What is correct?

thanks

Hello Kevin,

There is no issue at all, USB3 supports polarity inversion, the PHY detects the inversion during the enumeration and internally compensates its effect.

Regards,

Diego.
