ABSTRACT:
A data transmission apparatus has a timer circuit disposed to have time data input thereto. The time data specifies a time interval of transmission of main data which forms parallel data together with the time data. The timer circuit counts the time interval specified by the time data input thereto to generate a time-up signal upon completion of counting the time interval, and has next one of the time data input thereto upon generation of the time-up signal. A transmission clock-generating circuit frequency-divides a predetermined system clock to generate a transmission clock signal, and is responsive to the time-up signal delivered from the timer circuit, for correcting the phase of the transmission clock signal. A serial data transmission circuit is responsive to the time-up signal delivered from the timer circuit, for having the parallel data input thereto, and for converting the parallel data into serial data, based on the transmission clock signal delivered from the transmission clock-generating circuit, to deliver the serial data.
