Hi guys,
I'm getting a bit confused on how to correctly terminate connector shielding (like USB, D-SUB, or similar). For instance, most of the board I've seen uses the RC variant, like this one:
However, Texas Instruments uses a ferrite bead instead in one of their designs (Sitara Starterkit):
These are two completley different approaches. One shorts high frequencies to GND, the other blocks them. Which one is correct, or better said, when do I use one and when the other?
Thanks and best regards,
Marko
