Where's the eMarker chip in a USB cable? And what does it do?

This really interesting cable is the reason I bought a microscope. It has a clear case with a lot of unpopulated options on the circuit board and we can decipher the eMarker IC markings. The datasheet is completing the story, which makes the buy totally worth it.

5:28 - regarding the shield. Obviously the destructive test of cutting open the cable can show whether the shield is in place.

But perhaps there is some way to use an interference signal outside of the cable to see if that interference is attenuated within the cable?

You forgot to lookup up the vendor name using the vendor ID.

just because theres parts, doesnt mean they do the fact they can be seen under a nice clear cover to me suggests they are not functional but just bling

Do you have a special reason to wear those gloves in your videos ?

USB-C is the most stupid thing ever. Cables which look the same behave differently. Bad Idea!!
