Semiconductor integrated circuit with parallel/serial/parallel conversion

A semiconductor integrated circuit comprising:

• a plurality of first converters;
• a plurality of second converters;
• and
• a clock signal supply section for supplying a clock signal for synchronizing an operation of the plurality of first converters and an operation of the plurality of second converters,
• wherein each of the plurality of first converters converts a plurality of input data signals into a composite serial data signal and outputs the composite serial data signal,
• each of the plurality of second converters receives the composite serial data signal via a data signal wiring and converts the composite serial data signal into a plurality of output data signals,
• the clock signal is input into each of the plurality of first converters and the plurality of second converters via a clock signal wiring,
• each of the data signal wirings imparts a time delay to the composite serial data signal input into each of the plurality of second converters,
• the clock signal wiring imparts a time delay to the clock signal input into each of the plurality of second converters, and
• the wiring dimensions for the data signal wiring and clock signal wiring being larger than the wiring dimensions for the input data signals.
