Part Number: TUSB8041
I have some questions for TUSB8041 configuration.
Only one port(PORT1) is connected to external and power control is required for this port.
All other 3 ports(PORT2-4) are connected internally and power control is not required for them.
In this case, does the below configuration make sense?
FULLPWRMGMTz/SMBA1/SS_UP = 0
Unused OVERCUR2-4 = 10K ohm external pull-up
Unused PWRCTL2-4/BATEN2-4 = leave open
If using a port for only USB2.0, is it OK to leave open for USB_SSTX and USB_SSRX pins?
I want to use external clock source for input clock.
But the external clock is 3.3V signal. So I’m considering to use it with a resistor divider.
Does this way work? If it could work, how much ohms is good for this?
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to JMMN:
Thanks for your answer.
Regarding 1, could you tell me why FULLPWRMGMTz = 1 is better than 0?
