Adum4160 + ESD Protection

Hi,

can I use the ESD Protection as per schematic on the ADuM4160?  [It is to be on a peripheral]

PS- I do NOT want to use the PiC's   VUSB in this case... 

Thanks again!

PS:The process to get to this result is shown below:

    On the upstream side, the ADuM4160 has an integrated pullup, and you would be doubling up. So definitely do not use an integrated pull-up on the upstream side.

    I don't see that you need a filter on the downstream side at all. If you do use it, you need to base the integrated pullup on what the peripheral controller requires.

    I would also think about protecting the 5V power line with a diode on the cable side.
