Problems solved by technology
If one USB socket or UART socket is used for each system, the dual-standby and dual-pass system will use two USB sockets and one UART socket. To arrange so many sockets on the mainboard of the mobile phone will have a negative effect on the design. There are many unfavorable factors: first, the ID design of the mobile phone is not beautiful; second, the structural design will become very complicated
Third, the occupied hardware layout and the clearance area for RF antenna radiation have a great impact
Fourth, it will increase the BOM (BillOfMateriel) cost of the mobile phone

The invention discloses a bi-pass mobile phone platform USB socket, which comprises an application processor and a modem processor, wherein the application processor is provided with a USB I port and a USB II port; the modem processor is provided with a USB port and a UART port; the application processor and the modem processor are connected to a USB socket, and three two-way analog switches are arranged in a series connection mode between the USB socket and the application processor and the modem processor. The bi-pass mobile phone platform USB socket has the beneficial effects that requirements can be met by requiring only one USB socket through arranging three two-way analog switches on the application processor and the modem processor, thus design of a mobile phone chip is simplified, and the cost is reduced.
Description
technical field [0001] The invention relates to a mobile phone USB socket, in particular to a two-way mobile phone platform USB socket. Background technique [0002] Based on the current mainstream products in the market, all need to realize the scheme design of dual-standby and dual-pass system, and this scheme also has a good market prospect and is favored by consumers. However, for a handheld terminal device such as a mobile phone, it is necessary to integrate many functions into one device with a relatively small volume. There are great challenges for ID design, structural design, and hardware design. Therefore, the multiplexing design of communication interfaces should be implemented. And born. [0003] Due to the system solution of dual standby and dual communication, in the process of development and use, there will be requirements for downloading software, debugging and mutual communication between the two systems. To realize these functions and requirements, USB...
