W2L? Want 2 Learn?

USB-C cables require at least one controller (therefore called EMCA Electronically Marked Cable Assembly e.g. (CCG2 usb-C Controller Gen2) inside. See here part 1 and part 2 of a deep dive and a slideplayer presentation of Cypress. Finally a HighRes pic of receptables.

Have fun -)

Test yourself What sets a Passive EMCA apart from an Active EMCA?

Not really-really.

A USB-C cable can be EITHER EMCA or not

When is Electronic Marking necessary?

Electronic marking is needed in a Type-C Cable when any of the following apply

  • VBUS Current of more than 3 Amps is required
  • USB 3.1 Gen2, or 10GHz USB, is required
  • Alternate Modes are required

from point 2.4 (page 8).

I love standards, there are so many of them )
