TUSB544: SBU and AUX not used

Matiss Maltisovs

Part Number: TUSB544

Hi!

If SBU and AUX differential pairs will not be used, what would be the recommended way to terminate them?

As mentioned in datasheet - SBU_P & _N pull-down with 2Mohm,
AUX_P pull-up with 1Mohm,
AUX_N pull-down with 1Mohm?

Thanks!

Hi,

If your application uses USB only and does not use the USB-C DP Alternate Mode, then these pins can be left not connected. No additional termination required.
