Example one

The present embodiment provides an interface apparatus, as shown in fig. 1, the apparatus including:

an interface component 100, the interface component 100 comprising a first type interface 101 and a second type interface 102;

a switching module 200, wherein the switching module 200 is electrically connected to the first type interface 101, and the switching module 200 is electrically connected to the second type interface 102;

the switching module 200 turns on the first type interface 101 or the second type interface 102 based on the received control signal.

In a specific implementation process, the interface device provided by the embodiment of the application can be applied to electronic equipment such as a mobile phone, a camera, a television, a computer, a pad and the like. The interface device simultaneously provides different data transmission modes, and realizes interface multiplexing, thereby improving the utilization rate of the interface. The first type interface 101 may be a digital video port and the second type interface 102 may be a mobile industry processor interface.

A switching module 200 including a switch enable port En and a switch unit 220; the switch unit 220 is electrically connected with the first type interface 101, and the switch unit 220 is electrically connected with the second type interface 102; the switch enable port En is electrically connected to a control terminal of the switch unit 220 to control the switch unit 220 to be selectively turned on in one of the first type interface 101 and the second type interface 102.

The input end of the switch unit 220 is electrically connected to a plurality of pins output by the data processing module, and the first type interface 101 and the second type interface 102 have different data transmission modes and share the plurality of pins.

As an alternative embodiment, the data processing module output has ten pins, the first type interface 101 has ten ports, and the second type interface 102 has ten ports; ten ports of the first type interface 101 and ten ports of the second type interface 102 are electrically connected with the ten pins in a one-to-one correspondence manner.

In the specific implementation process, ten pins output by the data processing module are as follows: the pin-out structure comprises a first pin 1, a second pin 2, a third pin 3, a fourth pin 4, a fifth pin 5, a sixth pin 6, a seventh pin 7, an eighth pin 8, a ninth pin 9 and a tenth pin 10, wherein the pins are represented by the numbers 1-10 in the drawing, and the ports are represented by letters. Wherein, the first type interface 101 includes: d0, D1, D2, D3, D4, D5, D6, D7, D8 and D9, the second-type interface 102 including: D0P, D0N, D1P, D1N, D2P, D2N, D3P, D3N, CLKP, and CLKN.

Specifically, the first pin 1 is electrically connected to the port of the first type interface 101 through the switch unit 220, D0 and the first pin 1 are electrically connected to the port D0P of the second type interface 102 through the switch unit 220, and the first pin 1 is selectively conducted between the port D0 and the port D0P by controlling the switch unit 220 through the switch enable port En. Similarly, the second pin 2 is electrically connected to the port D1 of the first type interface 101 through the switch unit 220, and the second pin 2 is electrically connected to the port D0N of the second type interface 102 through the switch unit 220, so that the first pin 1 is selectively connected between the port D1 and the port D0N by controlling the switch unit 220 through the switch enable port En.

The third pin 3 to the tenth pin 10 are electrically connected to the port of the first type interface 101 in the same electrical connection manner, and the third pin 3 to the tenth pin 10 are electrically connected to the port of the second type interface 102 in the same electrical connection manner, which will not be described in detail herein.

As an alternative embodiment, the switch unit 220 includes a plurality of MOS transistor groups as shown in fig. 2, each of the MOS transistor groups is electrically connected to one port of the first type interface 101, and each of the MOS transistor groups is electrically connected to one port of the second type interface 102 to control the port switching of the first type interface and the second type interface. Thus, the conduction of the channel can be controlled only by inputting high and low levels to the grid of the MOS transistor group. Of course, the switch unit 220 may also include a plurality of transistors, and the above functions may also be implemented, and the embodiment is not limited.

Specifically, as shown in fig. 2, one of the MOS transistor groups includes a PMOS transistor P1 and an NMOS transistor N1; wherein the gate of the PMOS transistor P1 and the gate of the NMOS transistor N1 are both electrically connected to a switch enable port En; the source electrode of the PMOS transistor P1 and the source electrode of the NMOS transistor N1 are both electrically connected with one pin of the data processing module for inputting data; the drain electrode of the PMOS transistor P1 is electrically connected with a port of the first type interface 101; the drain of the NMOS transistor N1 is electrically connected to a port of the second type interface 102.

For example, as shown in fig. 2, the gate of the PMOS transistor P1 and the gate of the NMOS transistor N1 are electrically connected to the switch enable port En, the source of the PMOS transistor P1 and the source of the NMOS transistor N1 are electrically connected to the first pin 1 in fig. 1, the drain of the PMOS transistor P1 is electrically connected to the port D0 in fig. 1, and the drain of the NMOS transistor N1 is electrically connected to the port D0P in fig. 1. Thus, when the switch enable port En inputs a high level, the source and the drain of the NMOS transistor N1 are turned on, and the first pin 1 is turned on with the port D0P of the second type interface 102. When a low level is input through the switch enable port En, the source and the drain of the PMOS transistor P1 are turned on, so that the first pin 1 is turned on with the port D0 of the first type interface 101, thereby implementing switching between the first type interface 101 and the second type interface 102, and further implementing sharing of the first pin 1.

As an alternative embodiment, the interface device is an interface device of a camera unit.

As an optional embodiment, the data transmission mode of each group of ports includes a parallel output mode and a differential serial transmission mode. In a specific implementation process, when the type interface adopting the parallel output mode is electrically connected with the pin, the pin is equivalent to a DVP interface. When the type interface adopting the differential serial transmission is electrically connected with the pin, the pin is equivalent to an MIPI interface. And further, the same interface can realize the functions of multiple transmission modes.

For example, assume that the first type interface is an interface using a parallel output method, and the second type interface is an interface using differential serial transmission. When the switch enable port En inputs a low level, the source and the drain of the PMOS transistor in each MOS transistor group are turned on, and further, each pin is turned on with the first type interface 101, so that a parallel output mode is implemented, and the pin is equivalent to a DVP interface. When the switch enable port En inputs a high level, the source and the drain of the NMOS transistor in each MOS transistor group are turned on, and further, each pin is turned on with the second type interface 102, so that differential serial transmission is realized, and the pin is equivalent to an MIPI interface. Therefore, the same pins are adopted, and the switching of different types of interfaces can be realized through the control of the level, so that the multiplexing of the interfaces is realized, and the utilization rate of the interfaces is improved.

Example two

As shown in fig. 3, the present embodiment provides a control method for controlling an interface apparatus according to any one of the embodiments, the method including:

inputting a control signal to the switching module to control to open the first type interface or the second type interface;

if the control signal is at a low level, the first type interface is conducted; if the control signal is at a high level, the second type interface is conducted; and the first type interface and the second type interface have different data transmission modes.

For example, assume that the first type interface is an interface using a parallel output method, and the second type interface is an interface using differential serial transmission. When the control signal is at a low level, each pin is connected to the first type interface 101, so that a parallel output mode is realized, and the pin is equivalent to a DVP interface. When the control signal is at a high level, each pin is connected to the second type interface 102, so that differential serial transmission is realized, and the pin is equivalent to an MIPI interface. Therefore, the same pins are adopted, and the switching of different types of interfaces can be realized through the control of the level, so that the multiplexing of the interfaces is realized, and the utilization rate of the interfaces is improved.
