Abstract

A technique for establishing a network interface and an external interface in a connector is disclosed. A personal computer (PC) includes a device controller for controlling data transmission with a peripheral device and a network device, and a receptacle including multiple pins for connecting data channels of the device controller to the peripheral device through the external interface and the network device through the network interface. The PC further includes a crossbar switch for switching the data channels to establish the external interface and the network interface in the receptacle. The external interface complies with the USB standards, and the network interface complies with the Ethernet standards.

First claim

What is claimed is:

1. An electronic device comprising:
a host system;
a device controller includes a first data channel for communicating with a peripheral device and a second data channel for communicating with a network device;
a first receptacle for simultaneously providing a peripheral interface for said first data channel and a network interface for said second data channel;
a crossbar switch, connected between said device controller and said first receptacle, switches between said first and second data channels of said device controller to establish said peripheral interface and said network interface in said first receptacle; and
a power delivery controller connected to said host system via a first serial bus, and connected to said crossbar switch via a second serial bus.

2. The electronic device of claim 1 , wherein said peripheral interface includes a first external interface and a second external interface, and said crossbar switch selects one of a combination of said first external interface, said second external interface, and said network interface.

3. The electronic device of claim 2 , wherein said first external interface is a Universal Serial Bus (USB) interface, said second external interface is a display interface, and said network interface is an Ethernet.

4. The electronic device of claim 1 , wherein said first receptacle is of a Universal Serial Bus (USB) Type-C.

5. The electronic device of claim 4 , wherein said first receptacle further includes a reverse connection inhibiting structure for a plug to be connected to said first receptacle.

6. The electronic device of claim 5 , wherein said plug having said reverse connection is allowed to be connected to said first receptacle to establish a data channel for a USB interface.

7. The electronic device of claim 2 , wherein said crossbar switch establishes, between said device controller and said first receptacle, a data channel shared by said second external interface and said network interface.

8. The electronic device of claim 2 , wherein said device controller establishes, between said device controller and said first receptacle, data channels for said network interface.

9. The electronic device of claim 1 , wherein said host system is connected to said device controller via a data bus.

10. An electronic device comprising:
a host system;
a device controller includes a first data channel for communicating with a peripheral device and a second data channel for communicating with a network device;
a first receptacle for simultaneously providing a peripheral interface for said first data channel and a network interface for said second data channel, wherein said peripheral interface includes a first external interface and a second external interface; and
a crossbar switch, connected between said device controller and said first receptacle, switches between said first and second data channels of said device controller to establish said peripheral interface and said network interface in said first receptacle, wherein said crossbar switch selects one of a combination of said first external interface, said second external interface, and said network interface to provide a Universal Serial Bus (USB)+display port mode at said first receptacle.

11. The electronic device of claim 10 , wherein said crossbar switch selects said first external interface, said second external interface, and said network interface to provide a USB+Ethernet mode at said first receptacle.

12. An electronic device comprising:
a host system;
a device controller includes a first data channel for communicating with a peripheral device and a second data channel for communicating with a network device;
a first receptacle for simultaneously providing a peripheral interface for said first data channel and a network interface for said second data channel; and
a crossbar switch, connected between said device controller and said first receptacle, switches between said first and second data channels of said device controller to establish said peripheral interface and said network interface in said first receptacle, wherein said electronic device is connected to a function extender having
a second receptacle connected to said first receptacle of said electronic device;
a plurality of peripheral receptacles to allow a peripheral device to be connected to said electronic device;
a network receptacle to allow a network device to be connected to said electronic device; and
a crossbar switch to route data channels between said second receptacle and said peripheral and network receptacles.

13. The electronic device of claim 1 , wherein said device controller further includes a Universal Serial Bus controller, a display port controller and an Ethernet controller.
