Abstract
A transmission device includes: parallel/serial conversion units; a clock signal transmission unit; a known-parallel data generation unit for inputting known-parallel data to the parallel/serial conversion units; a clock shift unit for sequentially shifting a clock signal, which is outputted from the clock signal transmission unit, by 1 UI of a data signal; sampling units for sampling data signals obtained by serializing the known-parallel data, in accordance with the clock signal shifted by 1 UI; and a diagnostic processing unit for making a diagnosis as to whether the transmission device is operating normally by comparing sampling results with the known-parallel data, and outputting a result of the diagnosis.
