Hi,

I was wondering if there was a reference circuit for this part available I saw a this previous posting (https://e2e.ti.com/support/interface/f/138/p/673630/2479613?tisearch=e2e-sitesearch

Please see attached, I can also review your schematic if needed.

Thanks

Thanks for the fast response.

From the datasheet, it looks like DP_SEL and AUX_SEL are wired into the same pin (A1), Is there a way to separate the two as shown in the pdf?

My schematic is below: C is being treated as an downstream device, while A and B are two separate upstream (2:1).

thanks!

This portion of schematic looks ok, please make sure the input and output of HD3SS212 are properly biased.

Thanks
