+ TS3USB221 schematic review and questions

Part Number: HD3SS3202
Other Parts Discussed in Thread: TS3USB221, , TMUXHS4212

Hi HSSC team,

A key architect at Lab126 has requested a schematic review on the HD3SS3202 and TS3USB221 devices as per the attached. There are also additional questions as per below and would appreciate your feedback on the questions and designs.

  • What is maximum peak current in both parts?
  • I am connecting two USB3.0 switches together – because I have a Type C connector which requires the switch, and a second connector which I need to select to route to.  Have you seen this done?  With careful routing will I be OK or will this be too much insertion loss from part?
  • Do I need to add series capacitors on TX/RX between the switches?  I did not  add them between in my schematic right now
