Hi Harish,

Apologies for the delay, here is the schematic review:

TUSB1044_Schematic_Review_VVDN_701-1-05308(5_21_2025).pdf

These schematics look the same for redriver1 and redriver2, so I will complete only one. If there are any differences I didn't catch, I can do one for redriver1 as well.

Additionally,

Aux has 2 sets of PUP and PDOWNs, we need to remove one of them.

The ESD diodes used are discontinued from what I see.

I recommend the PUSB3FR4, if these cannot be used.
