Description
Technical field
The utility model relates to a kind of high-definition multimedia interface conversion device.
Background technology
At present, along with the issue of USB3.1 agreement and the popularization apple of application and each big IT electronics business release the electronic product of band based on the TYPEC interface of USB3.1 technology one after another, it not only solves the problem of positive anti-plug, and transfer rate can 10Gbps simultaneously. This interface size is little and can change out the audio-video signal of each class interface, eliminates conventional large size VGA, HDMI, DVI interface, greatly achieves the lightening of electronic product and attractive in appearanceization.
Practical novel content
The utility model, based on the indicating meter or the televisor that also do not have TYPEC interface at present, is developed USBTYPECTOHDMI transmodulator and is realized the object that smaller screen renders to large-size screen monitors simultaneous display.
It is as follows that the utility model solves the problems of the technologies described above the technical scheme taked:
A kind of high-definition multimedia interface conversion device, comprise: female seat and male, it is provided with signal conversion chip between the two, in addition, between described male and signal conversion chip, it is provided with master control chip MCU, communication interface conversion chip it is provided with between master control chip and male, in addition, two power conversion chips in parallel it are respectively equipped with between described male and signal conversion chip, wherein, described female seat is HDMI female seat, and described male is USB3.1TYPEC male.
After the utility model takes above scheme, it is backward compatible by this production interchange Cheng Chaoqing HDMI signal (resolving power supports 4KX2K/30HZ) resolving power based on the notebook of USB3.1TYPEC interface, flat board, mobile phone, has good effect.
Other features and advantages of the utility model will be set forth in the following description, and, partly become apparent from specification sheets, or understand by implementing the utility model. The purpose of this utility model and other advantages realize by structure specifically noted in the specification sheets write, claim book and accompanying drawing and obtain.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in detail, so that above-mentioned advantage of the present utility model is definitely.
Fig. 1 is the structural representation of the utility model high-definition multimedia interface conversion device.
Embodiment
Below in conjunction with specific embodiment, the utility model is described in detail.
As shown in Figure 1, a kind of high-definition multimedia interface conversion device, comprising: female seat and male, is provided with signal conversion chip between the two, in addition, it is provided with master control chip MCU between described male and signal conversion chip, it is provided with communication interface conversion chip between master control chip and male, in addition, two power conversion chips in parallel it are respectively equipped with between described male and signal conversion chip, wherein, described female seat is HDMI female seat, and described male is USB3.1TYPEC male.
Wherein, mode of operation of the present utility model is as follows:
When this transmodulator inserts source equipment, transmodulator is defaulted as from equipment by an identification resistance and exports 5V power supply and power to transmodulator by equipment. Chip start after obtaining electricity to run subsequently based on USB3.1TYPEC interface A5 at a high speed communication pin CC1 convert I2C agreement to by FUSB300 and be connected with micro-chip STM32L151RBH6, then shaking hands and data exchange of micro-chip STM32L151RBH6 and signal source equipment is realized, informing that primary device sends detection signal and displayport (high-definition digital display) signal, after obtaining displayport signal, signal conversion chip PS171 converts displayport signal to HDMI signal and delivers to rear end display equipment and show. This inventive structure is made up of the USB3.1TYPEC male of band line, PCBA and HDMI female. USB3.1TYPEC male is inserted signal source equipment, then connects HDMI display equipment, inside complete to communicate after output sound vision signal, it is achieved mirror image is with screen or expansion.
In addition, in embodiment without exception, USB3.1TYPEC male being inserted the signal source equipment of band female seat, the lower pull-up resistor output VCONN_3.3V recognizing 1K on B5 powers to master control chip STM32L151RBH6 and communication interface conversion chip FUSB300. Recognize on A5 pull-up resistor under 5.1K simultaneously, by A4A9B4B9 outwards for 5V power supply VBUS, convert 3.3V and VDD12 two voltages supply signal conversion chip PS171 respectively to by Power convert ICHX1151 immediately.
High speed signal pins A5 (CC1) converts I2C signalling methods to by communication interface conversion chip FUSB300 and is connected the signal communication realizing signal source equipment and micro-chip with master control chip STM32L151RBH6. Detect signal HPD when output equipment is received in HDMI female seat and become high feeding micro-chip, tell that signal source equipment goes to read rear end display equipment by A8 (AUX+) and A9 (AUX-) by signal conversion chip PS171 and can support that the state of which resolving power exports several groups of displayport signals to determine, the highest send four groups of ML (3:0) signals. Convert HDMI signal to by PS171 and go display to display equipment, the video resolving power of the highest support 3840*2160/30HZ and refreshing rate.
Useful effect compared with conventional art:
1, compensate on market the defect of the not display equipment of TYPEC interface based on up-to-date USB3.1 technology, it is achieved that smaller screen display interface mirror image or expand to large-size screen monitors object;
2, interface is not distinguished positive anti-plug and is avoided mishandle and save the plug time;
3, transfer rate improves greatly, can reach 10Gbps at full speed, can transmit more high-resolution audio frequency and video.
Finally it is noted that the foregoing is only preferred embodiment of the present utility model, it is not limited to the utility model, although the utility model being described in detail with reference to previous embodiment, for a person skilled in the art, technical scheme described in foregoing embodiments still can be modified by it, or wherein part technology feature carries out equivalent replacement. All within spirit of the present utility model and principle, any amendment of doing, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
