ABSTRACT:
A system for clock-switching applied in the field of integrated circuits is described. A phase interpolator converts an input clock signal into a clock_A and a clock_B having a phase difference therebetween and transmitting the clock_A and the clock_B. A switch command unit connected to the phase interpolator receives either the clock_A or the clock_B serving as a triggering signal for triggering the switch command unit to transform an input switching signal into an output switching signal when the output switching signal is located in either a rising or a falling edge. A selecting device connected to the phase interpolator and the switch command unit, selects either clock_A or clock_B according to the output switching signal from the switch command unit to output a clock-switching signal composed of clock_A and clock_B.
