I am designing a board with a USB 3.2 Type-C connector from Molex, and I understand that at a possible 10Gbps, this design is going to need to be very well laid out.

Is there somewhere a reference design showing one example of the PCB layout around such a connector?

According to the whitepaper Managing Connector and Cable Assembly Performance for USB SuperSpeed:

System OEMs should get the optimized PCB launch designs from the connector manufacturer for their own PCB stack-ups.

Has anyone ever seen such a design from a connector manufacturer?

  • \$\begingroup\$ Have you contacted the connector manufacturer to see if they can provide optimized PCB launch designes for their connector? (also known as "Final Inch" designs). \$\endgroup\$ Commented Mar 19, 2021 at 0:33
  • \$\begingroup\$ @TomCarpenter - I haven't tried contacting them. I just assumed that if they were available, they'd be on the web site. \$\endgroup\$ Commented Mar 20, 2021 at 22:11

    \$\begingroup\$ They don't aways provide information on the website. I've found Molex customer support quite responsive though. They may well have example designs or be able to provide pointers. \$\endgroup\$ Commented Mar 20, 2021 at 22:13

Not a connector manufacturer, but TI does have some good tips that might help you here: https://e2e.ti.com/support/interface/f/interface-forum/512449/type-c-connector-layout-made-easy
