Abstract: A transmission interface between at least a first module and a second module is proposed. The transmission interface includes at least two physical transmission mediums. Each physical transmission medium is arranged to carry a multiplexed signal in which at least two signals are integrated. The at least two physical transmission mediums include a first physical transmission medium arranged to carry a first multiplexed signal including a first IF signal and a reference clock signal. The first IF signal and the reference clock signal are at different frequencies.

Abstract: A power cable plug assembly having replaceable plug includes a plug seat, and a plug. The plug seat has a side face formed with a locking recess formed with a first catch plate and a second catch plate. The plug is provided with a first snapping portion combined with and rotatably mounted on the first catch plate of the plug seat and a second snapping portion combined with the second catch plate of the plug seat. Thus, the power cable plug assembly having replaceable plug can replace different plugs of different kinds and sizes, thereby enhancing the versatility of power cable plug assembly having replaceable plug.
