Hi Team,

I'm using ISOUSB211DPR USB2.0 isolator in my board.

Please find the attached schematics of the isolator, request you to review and provide the feedbacks.

Hi Abhishek,

This post seems to be duplicate of already clarified query here: (+) ISOUSB211: Design Inquiry - Isolation forum - Isolation - TI E2E support forums

I have only one comment to add with respect to decoupling capacitor values and selection. Please make sure that section 8.3 (Power Supply Recommendations) are followed strictly here - which I don't see is being followed here in the schematics.

You can also refer ISOUSB211 EVM schematic for reference and BoM table for component selection: ISOUSB211DPEVM Isolated USB Evaluation Module
