Configuration ChannelProviding the flexibility of Type C

Functionally the Configuration Channel (CC) is used to serve the following purposes:

Detect connect of USB ports,

Resolve cable orientation and twist connections to establish USB data bus routing

Establish DFP (sink) and UFP (source) roles between two

connected ports

Discover and configure power: USB Type- C current modes or USB Power Delivery

Discovery and configuration of optional Alternate and Accessory modes

Typical CC flow for DFP to UFP configuration:

Detect valid connection Establish USB power method Configure as a DFP or UFP



Typical Behavior upon Attachment

The CC2 / CC line shows the voltages on the configuration channel between the sink

and a source that applies VCONN to the cable.

t1: the cable is attached.

t2: the source confirms a valid sink is attached,

then applies 5V to VBUS and VCONN.

t3: USB Type C 3A advertisement begins &

USB PD messaging begins on CC line

t4: VBUS voltage is increased to negotiated level.

layer description




This corresponds to a line impedance of approximately 53 Ω.




VIA preperation:

Without rest ring is important

to avoid capacitive and

inductive effects between

the layers.




Attenuation:




Attenuation D1 – D1:

(S12 – S34)

Attenuation D2 – D2:

(S32 – S41)

Pairs of datalines are nearly simmilar!




Attenuation and

crosstalk:




Room Temp. 23°C

5A / 20V




Key features of this new connector:

Higher durability

Higher data rate

Higher current capability (Power supply)

Reversibility feature

Short Type (for integrated applications)

Compatibility with different protocols:

HDMI

Thunderbolt…
