Integrated signal multiplexing circuit with four input paths, including a phase generator circuit 1 and 2, a phase shaping circuit 3 and an input signal serialising circuit 4 characterised in that the phase generator is formed of two flip-flops 1 and 2 controlled by the same clock signal C, the first of which receives as input the outputs fed back from the second flip-flop and delivers at output a first phase signal Q1 and its complement@, and the second of which receives as input the first phase signal and its complement and delivers at output a second phase signal Q2 and its complement@, and in that on the one hand, the first and the second phase signals have a frequency which is a quarter of the frequency of the clock signal C, and on the other hand, the first and second phase signals are pi /2 out of phase. Application: ultrafast integrated multiplexers. <IMAGE>
