The capacitor is there to build a low impedance path for high frequencies.
So it´s on the application
* what frequencies you want to focus on
* what impedance you want at these frequencies
and the resistor is there to suppress static charge.

Thank you for the clarification. Ok, so the capacitor I need to select based on the frequency. So, I need to calculate based on the Xc = 1/(2pifC) formula, right? In that case, what should the frequency I need to be focusing on 100/1000BASE-TX ethernet and USB 2.0/3.0? Any idea on this?
Also, can you explain how the resistor helps to suppress static charge and how to arrive at the value of R? Which formula to use?
