TUSB546A-DCI: Schematic Review

I've uploaded my Design Smart PDF in the attached Google Drive.

Hi Tyler,

Thanks for your patience.

Here is the review:

1) Replace these with 330nF capacitors

2) Why do you have two USB-C connectors? Is this for the flip orientation? I haven't seen a connector shown like this before.

3) The line capacitance of the ESD may be a bit high at .42pF. I recommend a line capacitance of approx. 0.25pF with a clamping voltage of about 5V.

4) This mean AUX snooping is always enabled, is this correct? Will this part only be used in GPIO mode?

I will reassign to PD to review the schematic of the PD controller.

Also have a look at the TUSB546 EVM schematics for a reference if needed.

1) Okay

2) This is to simplify the schematic. It's one connector but it's displayed as Part A and Part B to make it easier to read.

3) Okay. I will find something closer to 0.25pF to use.

4) I'm designing in the option for it to be used in either mode depending on BOM population. I would prefer using it in GPIO mode when everything is tested and tuned properly. 

Hello,

Please use the attached checklist for schematic review.
