摘要： The disclosed embodiments relate to a communication circuit (100). An exemplary embodiment of the communication circuit (100) comprises a first branch (101, 103) adapted to operate at a first signal voltage level, a first source voltage contact (105) adapted to deliver a voltage corresponding to the first signal voltage level to the first branch (101, 103), a second branch (107, 109) adapted to operate at a second signal voltage level that is higher than the first signal voltage level, a second source voltage contact (111 ) adapted to receive a voltage corresponding to the second signal voltage level via an external connector(136) and to deliver the voltage corresponding to the second signal voltage level to the second branch (107, 109), and a voltage selection circuit (126) coupled to the first source voltage contact (105) and the second source voltage contact (111 ), the voltage selection circuit (126) configured to provide the first signal voltage level to the first branch (101, 103) and the second signal voltage level to the second branch (107, 109).
