Hi Expert,

Why do we need two different cap for two different GND? What's  the difference between these two GND? I suppose they are the same? Thanks.

    Hi Elec,

    This is in a situation where a GND network is used - meaning a diode and a resistor is in parallel between IC_GND and Systen_GND. The cap there is for both IC_GND and System_GND EMI and voltage stabilization. Please let me know if you have additional questions.
