Abstract: A multiple-phase switching circuit includes an alternative signal generator for generating a plurality of alternative signals according to a switching signal, and a multiplexer for receiving a plurality of clock signals and outputting a target clock signal according to the alternative signals. Only one of the alternative signals generated by the alternative signal generator is in a first logic level, while the other alternative signals are in a second logic level. The alternative signal generator changes the logic level of a first alternative signal having the first logic level into the second logic level, and changes the logic level of a second alternative signal adjacent to the first alternative signal into the first logic level.

Abstract: The invention provides a serial link transmitter coupled to a serial link receiver through a pair of transmission lines and having a pair of transmitting terminals respectively coupled to one of the transmission lines. The serial link transmitter comprises a differential amplifier and a voltage clamping circuit. The differential amplifier generates a pair of differential output voltages on the transmitting terminals according to a pair of differential input voltages for transmitting data to the serial link receiver, and the differential output voltages are transmitted with a common mode voltage to the serial link receiver during data transmission. The voltage clamping circuit clamps the pair of differential output voltages of the transmitting terminals to the common mode voltage before the serial link transmitter transmits data to the serial link receiver.
