When you think of USB Type C, what do you think of?

A thin interface?

Will it only appear on your laptop or phone?

Is all this really as simple as a USB interface?





I (Type C)

In fact, there is also a variety of modes

English name Alt Mode I really don't know how to translate Chinese into English.

When people say that Buddha has everything, they are referring to the Alt mode of Buddha.

Others say I have one System Interface Jianghu Ambition

In addition to USB2.0\USB3.0\USB3.1

I also want to use HDMI\MHL\DisplayPort

\Thunderbolt and others were included in his team


In fact, I never took over them. It was their international standards organization that came to me and dressed me up as a versatile goddess, hoping that I could use a thin interface and a familiar face to connect to various buses.




But

How to become a qualified versatile goddess?


Just like every child's growth process

To be recognized by this society, various certificates are essential


"I said I can support up to 100W of charging and discharging"

I have to show the USB PD compliance test certificate


I said I support DisplayPort

I have to produce the DisplayPort conformance test certification


Even if I transform into a cable

I also want to provide USB Type C cable conformance test certification


There is also a certificate that is the most difficult to obtain, which is Thunderbolt

This bus interface is too abnormal

The signal rate is up to 20GSa/s

Among all the changes, the most difficult one is to become her


Because of the various modes of Type C, it must undergo rigorous verification and testing before it is launched on the market. Want to fully understand Type C Alt mode and its testing? An application note compiled by Keysight Technologies will give you a comprehensive and beneficial understanding.
