Hi there,
I have a few questions regarding the TUSB2046B device.
1) Is the 33 Ohm series termination resistors and 1.5K pull up resister required if the hub is embedded on the PCB. Meaning, that is never detached from the processor host port. Copper on the PCB has been routed as 90 Ohm diff pair, no cabling.
2) Is the TUSB2046 capable of enabling/disabling the /POWERON signal from an upstream port? Or is the /OVRCURRENT input the only option?
3) Looking at the 2.0 compliance checklist, there is a section 4.2 Bus Power and subsection BP2 requests: Does the hub allow host controlled power switching of its downstream ports?
Look forward to any feedback you are able to provide us.
Thanks
