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 transmission interface between at least a master module and a slave module is proposed. The transmission interface includes a predetermined number of physical transmission medium(s). Each physical transmission medium is arranged to carry a multiplexed signal in which at least two signals are integrated, and the predetermined number is not smaller than a number of intermediate frequency (IF) stream(s) to be transmitted.

Abstract: The invention provides method and associated signal system improving mitigation of injection-pulling effect for an oscillator which generates an output clock under control of a control signal. The method may include: by a loop filter, filtering a deviation signal to form a filtered signal; by a SIL (self-injection locked) controller, forming an auxiliary signal which tracks the deviation signal or a phase difference between a reference clock and an output signal resulting from the output clock; and, forming the control signal by summing the filtered signal and the auxiliary signal.
