When electronic device design, in order to strengthen compatibility, often need to support polytype function, for example, support DP (DisplayPort simultaneously, display interface) and two kinds of interface functions of HDMI (High Definition Multimedia Interface, digital multimedia interface), according to different customer demands, can select wherein a kind of interface to use.In prior art, there are two kinds of implementations: a kind of is that DP and two interfaces of HDMI are set on electronic equipment, use respectively as required DP or HDMI plug, yet the method takies two per-interface space, use two groups of signal sources, in miniaturization electronic equipment, use inconvenient; Another kind is DP and HDMI to be made to the connector of up-down structure, yet the method also needs to take two per-interface space, uses two groups of signal sources, uses equally inconvenient at miniaturization electronic equipment.
Utility model content
The problem existing for prior art, the purpose of this utility model is to propose a kind of connected structure, mainboard, cabinet and electronic equipment thereof that shares two class interfaces, to solve two interfaces in prior art miniaturization electronic equipment, takies the wasting of resources problem that different spaces causes.
For reaching this object, the utility model by the following technical solutions:
A connected structure that shares two class interfaces, comprising: the first connector, the second connector and interface circuit; Described the first connector and the second connector comprise respectively data-interface, clock interface and power interface, and described the first connector and the second connector are dissimilar;
Described interface circuit comprises: the option interface that simultaneously adapts to the first connector described in data-interface, clock interface, power interface and the choice for use of described the first connector and the second connector or the second connector.
Preferably, described interface circuit also comprises: hot-plug interface.
Preferably, described the first connector is display interface DP connector, and the second connector is digital multimedia interface HDMI connector.
Preferably, described option interface connects low-voltage for connecting DP connector, connects high voltage for connecting HDMI connector; Or connect high voltage for connecting DP connector, connect low-voltage for connecting HDMI connector.
Preferably, described HDMI connector inside is provided with level shifter.
A mainboard, comprises the interface circuit in above-mentioned connected structure.
A cabinet, comprises above-mentioned mainboard.
An electronic equipment, comprises above-mentioned mainboard.
Compared with prior art, the utlity model has following beneficial effect:
In the utility model, two types of interfaces share same interface encapsulations, at the same interface two kinds of connectors of can selecting to peg graft, to realize, support two kinds of interface functions; And these two kinds of interface functions are used same group of signal source and clock, take same per-interface space, can save PCB space from connecting up, make periphery signal lead easier, can make more function be integrated on same mainboard, be applicable to miniaturization electronic equipment.
Accompanying drawing explanation
Fig. 1 is the interface circuit structure figure of the utility model embodiment.
Embodiment
The utility model embodiment provides a kind of connected structure that shares two class interfaces, comprising: the first connector, the second connector and interface circuit; Described the first connector and the second connector comprise respectively data-interface, clock interface and power interface, and described the first connector and the second connector are dissimilar; Described interface circuit comprises: the option interface that simultaneously adapts to the first connector described in data-interface, clock interface, power interface and the choice for use of described the first connector and the second connector or the second connector.Described the first connector is display interface DP connector, and the second connector is digital multimedia interface HDMI connector.Described option interface connects low-voltage and uses DP connector, connects high voltage and uses HDMI connector; Or connect high voltage use DP connector, connect low-voltage and use HDMI connector.
In the utility model embodiment, take and share DP and HDMI interface and describe as example, this interface circuit as shown in Figure 1, is 20 mount structures, and concrete pin definitions is as shown in table 1:
Table 1:
Wherein, pin one to 12 is public as data and the CLK signal of DP/HDMI; Pin 3 is DP or HDMI as the connector that detects examination use, when pin 3 drags down, for using DP connector, uses HDMI connector when pin 3 is drawn high; Pin one 5 and 17 is used as DP AUX/HDMI SMBUS, can realize by the adjustment on connector structure; Pin one 8 is hot plug use; Pin one 9 is power supply use; Pin two 0 is power supply ground.
In addition, when using HDMI connector, have and whether support two kinds of models of deep color (dark color), dark function can make the effect of display device be promoted to billions of colors from millions of colors, can allow consumer on display device, appreciate lively real color not seen before.When the scheme without supporting deep color, can directly use HDMI connector, when supporting the scheme of deep color, can be levelshifter (level shifter, between 3.3V and 5V system, provide level shift, to allow HDMI transmitter, receiver and the EEPROM of low voltage to be connected with 5V DDC bus) line related is arranged on HDMI connector inside, to save the design space of interface circuit.
The utility model embodiment provides a kind of mainboard, comprises the interface circuit in above-mentioned connected structure.
