Video signal；One pair of which is converted into USB3.0hub；Last is to changing into RJ45.
UFP:Upstream Facing Port, i.e. uplink port.
DRP:Dual Role port, computer or handset port, when to adapter, it is UFP (Upstream
Facing Port, from equipment), receive adapter and carry the power supply come；When connecing Dongle (receptor) again, it is DFP, to
The lower various data of transmission.
PD chip: be responsible for resolving the CC agreement of DFP Yu DRP.
GL3520 (chip): USB chip, a pair differential data in TYPE-C is converted into three USB3.0 interfaces.
RTL8153 (chip): TYPE-C is converted into RJ45 network interface.
DP exports: the DP video signal in output TYPE-C interface.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, it is possible to realize this practicality in other specific forms new
Type.Therefore, no matter from the point of view of which point, all should regard embodiment as exemplary, and be nonrestrictive, this practicality is new
The scope of type is limited by claims rather than described above, it is intended that by the containing of equivalency in claim that fall
All changes in justice and scope are included in this utility model.Should not be considered as any reference in claim limiting
Involved claim.
Although moreover, it will be appreciated that this specification is been described by according to embodiment, but the most each embodiment only wraps
Containing an independent technical scheme, this narrating mode of description is only that for clarity sake those skilled in the art should
Description can also be formed those skilled in the art through appropriately combined as an entirety, the technical scheme in each embodiment
May be appreciated other embodiments.
