Claim:
1. A system, comprising: a first transmitter, for transmitting a first signal to a first transmission line; a second transmitter, for transmitting a second signal to a second transmission line; a third transmitter, for transmitting a third signal to a third transmission line; a coding jitter detector, for generating a coding jitter determination result according to a state transition of the system; and a controller, coupled to the first transmitter, the second transmitter, the third transmitter and the coding jitter detector, for setting impedances of the first transmitter, the second transmitter and the third transmitter according to the coding jitter determination result; wherein when the state transition of the system belongs to a first group, the controller sets the first transmitter, the second transmitter and the third transmitter to have different impedances; and when the state transition of the system belongs to a second group, the controller sets the first transmitter, the second transmitter and the third transmitter to have substantially same impedances.
