Parallel-to-serial conversion circuit, information processing apparatus, information processing system, and parallel-to-serial conversion method
Parallel-to-serial conversion circuit, information processing apparatus, information processing system, and parallel-to-serial conversion method
A parallel-to-serial conversion circuit includes a plurality of parallel-to-serial conversion units, each being configured to include a dividing circuit configured to divide a clock signal having a second clock cycle to generate a clock signal having a first clock cycle, a parallel input circuit configured to input a signal having a plurality of bits parallel to one another in the first clock cycle, and a serial output circuit configured to serially output the signal having the plurality of bits input to the parallel input circuit bit-by-bit in the second clock cycle, wherein, among the plurality of parallel-to-serial conversion units, one of the dividing circuits has a synchronization signal interface that causes an output clock signal to synchronize with a clock signal output from the other dividing circuit in another parallel-to-serial conversion unit.
