Cyclone V (5CSXFC6D6F31C6) DE10 input 5V differential line (RS485)

Hi All, 

 

can I connect 5V to DE10 GPIO according to this using 160 Ohm?

(page 3) 

 

Is Cyclone V clamp appropriate for this? 

How can I check it? 

 

Thanks for consistent answer!

The fact that the PCI clamp isn't working before the device is configured can be reason enough not to rely on it.
