Embodiment Construction

[0038] The following provides an embodiment of a circuit structure sharing a bus in an electronic device, so that multiple signals can share the same bus and connector, and the signal quality can be maintained.

[0039] The following example takes a data bus compatible with two high-speed data bus standards as an example, for example, it is compatible with the standard based on Universal Serial Bus (Universal Serial Bus, USB) and Mobile High-Definition Link (Mobile High-Definition A data bus of Link, MHL) is taken as an example. The circuit structure in the embodiment allows at least three signals to share the same bus and connector. In some embodiments, the connector is, for example, a connector conforming to the USB standard, or a connector based on the USB standard, such as micro-USB or mini-USB, or a connection based on the USB standard and other self-defined connection lines device.

[0040] In some embodiments, a switch device with a wider bandwidth is used to selectiv...

Abstract

The invention discloses an electronic device with a circuit structure for sharing a bus. The electronic device disclosed by the embodiment comprises a connector, a data bus, a first group of switch devices, and a first control unit, wherein the first group of switch devices comprise a first switch device and a second switch device; one end of the data bus is connected to the connector; the output port of the first switch device is connected to the other end of the data bus, and selectively permits one of a first signal and a second signal to pass through; the transmission frequency of the first signal is substantially equal to the frequency width of the first switch; the output port of the second switch device is connected to the data bus, and selectively permits a third signal to pass through; the first control unit controls the first group of switch devices to selectively permit one of the first group of signals to pass through the data bus and the connector, and the first group of signals comprise the first signal, the second signal and the third signal.

Description

technical field [0001] The present invention relates to an electronic device, and in particular to a circuit structure sharing a bus in the electronic device. Background technique [0002] Portable devices such as smartphones, multimedia players, personal digital assistants, and digital cameras are now items that users often carry with them due to their ease of use. In order to enhance the connectivity of the portable device to extend other functions, the industry proposes a variety of different buses, so that the portable device can be further combined with other applications. Among many standards, Mobile High-Definition Link (MHL) is a new standard compatible with High-Definition Multimedia Interface (HDMI), which defines the A video and audio output format that allows mobile devices to connect to high-definition televisions or other compatible display devices. [0003] MHL currently adopts the most popular connection methods, such as connectors and buses based on USB st...
