<p>PURPOSE: To multiplex input data including the data indefinite area of more than one cycle without using a large-sized device with large power consumption such as an elastic storage and a memory, etc. CONSTITUTION: A flip-flop (F/F) 1 retimings the input data i1 by clocks CLK, the F/F 2 retimings the input data i2 including the data indefinite area of more than one cycle of the clocks CLK by the clocks CLK and the F/F 3 retimings control signals S by the clocks CLK. The F/F 4 delays the data D2 retiminged in the F/F 2 and generates the data D2'. A 2-1 selector 5 multiplexes the data D1 retiminged in the F/F 1 and the data D2' delayed in the F/F 4 by the control signals S' retiminged in the F/F 3. The F/F 6 applies waveform shaping to the data Dy multiplexed in the 2-1 selector 5.</p> |
