Hi Udesh,

Here is the schematic review.

TUSB1044_Schematic_Review_VVDN_701-1-05308(5_14_2025).pdf

I have one concern where there is only one PD controller for both the redrivers as here are 2 USB0-C port sin the system its standard to use a PD controller for each. Does the CYPD622 have the ability to be a PD controller for two USB-C ports?
