I'm looking at the schematic of a breakout board for
FUSB302 (Programmable USB Type-C Controller with PD).
The schematic (attached) has 470pF caps between the CC1/CC2 lines and ground.
The official breakout board (
https://www.onsemi.com/pub/Collateral/EVBUM2509-D.PDF, page 3) also has caps, only 200pF.
I can't seem to find any docs about the purpose of those caps. Would appreciate if someone could explain why they're needed.
(I'm designing an FUSB302-based USB-PD sink, for my own amusement/education, and am trying to figure out whether I should include these caps and how to choose them.)
