A frequency divider DIV/4 composed of memory cells (DL1 . . . DL4) realized in ECL technology, whose data paths constitute a loop, the data output Q4 of the last memory cell DL4 being cross-connected to the data input D1 of the first memory cell DL1. The clock inputs Ck of the memory cells DL1, DL3 of the odd rank are connected to the input IN of the frequency divider circuit DIV/4, while the others are cross-connected to said input. Such a frequency divider generates a noise having a unique frequency which is twice the frequency of the input signal, irrespective of the division ratio obtained.
