• Dn1 and Dn2 are short (from Notes.2)
• SBU1 and SBU2 are open (from Notes.3)
• All VBUS shorted (from Notes.4)
• All GND shorted (From Notes.5)

Also, regarding CC1, there is information on Silicon Labs' community forum,

• CC1 is pulled down with 5.1kΩ (from Silicon Labs community forum)

becomes.

Based on the above, the connection between the Type-C connector and the CP2102N is as shown in the figure below.

Silicon Labs does not have a recommended circuit for connection with the Type-C connector, and the evaluation board does not use a Type-C connector. Thank you for your kind judgment.
