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 )

iPhones 8, 8 Plus and X enable fast charging (non tech defined) over Power Delivery PD. Here the USB IF intro for PD and the supported profiles. QC Quick Charge 4.0 will be equal to PD 3.0 by the end of 2017.
