HD3SS3212-Q1: Can this model be used for PCIE 1:2

Hi,

Can this model be used for PCIE 1:2,？the input mentioned on the block diagram can be PCIE control, output one is  PCIE, another  one  is  USB control ？ can it output two PCIE control?

Yes,

Is there a PCIE3.0 switch, one input and two outputs?

You can use HD3SS3212 or TMUXHS4212.
