Description
Technical field
This utility model is related to a kind of two-in-one interfaces transducer.
Background technology
With the high speed development of electronics technology, common HD video（1080P）People cannot be met clear to video
The appreciation of degree requires, therefore DP is proposed 1.2,1.3 or even 1.4 standard and can support that 4K2K/60HZ's and 8K is super clear
Degree video.HDMI is also proposed the super definition that 2.0,2.2 standards can equally respectively reach 4K2K/60HZ and 8K.But in electronics
Product pursue under frivolous overall situation a lot of signal source equipments especially Fructus Mali pumilae equipment choosing MINI DP and abandon HDMI,
But the display device television set that is on the forefront of HDMI standard is not furnished with DP interfaces and is connect using HDMI high-definition multimedias
Mouthful.Therefore to realize that smaller screen is mirrored to large-size screen monitors and realizes that the display of ultra high-definition is accomplished by coming in fact by ultra high-definition interface convertor
Existing.The two-in-one interfaces transducer can meet the display to ultra high-definition video, and being furnished with USB interface meets making for multiple occasions again
With.
Utility model content
This utility model meets the demand that people show to ultra high-definition video large-size screen monitors, simultaneous with USB interface, can throw
Use on shadow instrument and the display device with VGA.
The technical scheme taken by this utility model solution above-mentioned technical problem is as follows：
A kind of two-in-one interfaces transducer, including：Female seat and male, are provided with signal switching chip between the two and signal turns
Chip is changed, additionally, the power conversion chip that 3.3V turns 5V between the male and signal conversion chip, is provided with, wherein, the mother
Seat is HDMI female seats and VGA female seats, and the male is Displayport males；The signal switching chip is arranged and is turned with signal
Change between chip and male, and signal switching chip is Displayport electronic commutators；The signal conversion chip
Turn VGA chips for Displayport and Displayport turns HDMI chips.
Preferably, interface of the Displayport males for Dp1.2 specifications.
Preferably, interface of the HDMI female seats for HDMI2.0 specifications.
After this utility model takes above scheme, which is based on the notebook of DP1.2 interfaces, computer main board, by being somebody's turn to do
Production interchange is into ultra high-definition HDMI2.0 signals（Resolution supports 4KX2K/60HZ）With VGA signals, HD video is not only met
Demand, and extending interface makes use range broader.
Other features and advantages of the utility model will be illustrated in the following description, also, partly from description
In become apparent, or by implement this utility model and understand.The purpose of this utility model and other advantages can pass through
In the description, claims and accompanying drawing that is write, specifically noted structure is realizing and obtain.
Description of the drawings
Below in conjunction with the accompanying drawings this utility model is described in detail, so that above-mentioned advantage of the present utility model is more
Clearly.
Fig. 1 is the structural representation of this utility model HDMI transducer.
Specific embodiment
Working method of the present utility model is as follows：
As shown in figure 1, a kind of two-in-one interfaces transducer, including：Female seat and male, are provided with signal switching core between the two
Piece and signal conversion chip, additionally, the power conversion chip that 3.3V turns 5V between the male and signal conversion chip, is provided with, its
In, the female seat is HDMI female seats and VGA female seats, and the male is Displayport males；The signal switching chip is arranged
Between signal conversion chip and male, and signal switching chip is Displayport electronic commutators；The signal
Conversion chip turns VGA chips for Displayport and Displayport turns HDMI chips.
Preferably, interface of the Displayport males for Dp1.2 specifications.
Preferably, interface of the HDMI female seats for HDMI2.0 specifications.
After this utility model takes above scheme, which is based on the notebook of DP1.2 interfaces, computer main board, by being somebody's turn to do
Production interchange is into ultra high-definition HDMI2.0 signals（Resolution supports 4KX2K/60HZ）With VGA signals, HD video is not only met
Demand, and extending interface makes use range broader.
Specifically, when the DP males insertion source equipment of the transducer, equipment immediately exports 3.3V power supplys to transducer
Power supply, makes while 3.3V being raised to 5V by booster power IC and supplying HDMI electrical switches HD3SS215 and HDMI, DVI female seat
With.When insert VGA line when, DP turn when VGA chip RTL2166 detect RGB enable foot HPD1 uprise feed back to DP electronics switching
Switch HD3SS215 draws high the HPD of DP male inputs, and now signal source knows that rear end connects outut device, by AUX+
AUX- goes the EDID situations for reading VGA display devices, then exports the DP signals of optimum resolution, is converted into R G by RTL2166
B analogue signals are sent to display device and show；
When HDMI is inserted, DP turns the HHPD of HDMI chip PS176 and uprises, then passes through DP electronic switch HD3SS215
Draw high the HPD of DP male inputs, then signal source equipment reads the EDID information of rear end display device, output by AUX
Optimum resolution DP signal, then HDMI2.0 ultra high-definition signals are converted into by PS176, then it is input to the output of HDMI ends.
Two mouths of the two-in-one transducer can not be exported simultaneously, and the priority of HDMI, VGA can be set in design
Put, the priority of this transducer is HDMI>VGA, two output priority Gao Na roads signals when connecing simultaneously.
Beneficial effect compared with conventional art：
1st, HDMI can support that 4K2K/60HZ ultra high-definitions show；
2nd, support that two mouthfuls of output use ranges of HDMI, VGA are wider；
Finally it should be noted that：Preferred embodiment of the present utility model is the foregoing is only, this is not limited to
Utility model, although being described in detail to this utility model with reference to the foregoing embodiments, for those skilled in the art
For, which still can be modified to the technical scheme described in foregoing embodiments, or to which part technical characteristic
Carry out equivalent.All of the present utility model spirit and principle within, any modification, equivalent substitution and improvements that is made etc.,
Should be included within protection domain of the present utility model.
