USB COMMUNICATION DEVICE IN A MOBILE TERMINAL, ESPECIALLY CONCERNED WITH IMPROVING THE AIR SENSITIVITY OF A MOBILE TERMINAL BY APPLYING A FILTER TO A DATA LINE IN CASE THAT THE MOBILE TERMINAL EXECUTES USB COMMUNICATION WITH ANOTHER COMMUNICATION EQUIPMENT

摘要

Purpose: it is arranged to prevent air sensitivity from declining in a USB communication device of a mobile terminal, it generates, if a mobile terminal attempts USB (Universal serial bus) and another communication apparatus communication, passes through one LC low-pass filters of application and cancel a undesirable noise component(s). Construction: including a USB drivers IC (201) and a LC low-pass filters (202) in a USB communication device of a mobile terminal. USB drivers IC (201) a, wherein USB port is mounted, with another communication unit according to the interface information of USB communication standard. LC low-pass filters (202) remove a noise component(s) and enhance air sensitivity.
