The CPU area bus 152 or direct connection is electrically connected to a main B controller 153, and the host USB controller 153 is electrically connected to the bus ^ to come in 1 machine 15 or a differential! With this; digitize 1 degree. For J must be phase 1 ‘data / a terminal line phase oblique cancellation 4

Also 'USB standard-USB 19, a physical transmission line, which is mainly a four-wire structure, which is a VBUS, D +, D- and ground wire, using D + and ^ data transmission, and VBUS The power can be selected from a USB host-one power supply (not shown). Since] and D — are designed for (Differential Pair) circuits, the client USB physical layer 1 15 and the host USB physical layer 155 must be used as the device for number transfer, and the same data transfer cycle can be realized by this There are some inevitable component designs in the USB physical layer 115 or host USB physical layer of each client, such as the lock-to-loop (pLL) pulse-recovery circuit (D ata / C 1 〇ck R ec verver) and the transmission wheel. Transmission Termination), and these components will have a large amount of working current, at least above 5 5 m A. Because of the client USB physical layer 115 or the host USB physical layer 155, the design and use of the USB transmission interface device are both faced with :: $ this problem ', that is, each component has a limit on the amount of working current that can be drawn, otherwise two components It will be seriously affected and hindered during operation. The above-mentioned restrictions on design or use are particularly serious for those portable or operating USB transmission interface devices, such as consumer products or mobile devices, which make them unable to play an appropriate role. Avoiding the USB host will not only increase the difficulty of the design of the USB transmission interface device.

M258347 Fourth, the creation instructions (3) seriously affect the trouble of the USB transmission interface device in use. [Creation content] Therefore, how to design a novel USB transmission interface device, especially a USB transmission interface device that can effectively reduce the amount of working current, which can benefit the convenience of product design and use, this is the creation Focus of creation. The main purpose of this creation is to provide a U g B transmission interface device that can replace the USB physical layer and "
