Hello TI team,
to minimize the number of unique ICs on the board, we will be using the TUSB1146 to multiplex the Host USB 3.2 lines onto the Type-C connector, but will have no connections to any DisplayPort signals, including AUX and SBU. (Meaning operation in USB only mode or shutdown mode).
Could you please confirm either way (No DisplayPort functionality needed):
1. Can the AUX pins on the 1146 be left open or do they still need the pull-ups/ pull-downs?
2. Can the SBU pins be left open or do they still need the pull-downs?
3. Can the DP Main Link lines be left open?
Thanks in Advance,
Daniels
