Summary: | PURPOSE:To eliminate the need for any special consideration synchronizing a clock of a transmission system and an output data of a computer by applying parallel/serial conversion to multiplexed 1, 0 bits alternately in a rate being the result of dividing a transmission rate of a transmission system by a parallel data number. CONSTITUTION:An output of a clock signal oscillator 4 deciding the transmission rate of an optical transmission system becomes a clock of a P/S converter 2, counted down by a counter 5 of N-count and inputted to a T-FF6. The output of the T-FF6 is inputted to the P/S converter 2 as bits A1 being alternate outputs of bits 1, 0 in a rate being the result of the transmission rate of the transmission system by a parallel data number together with a parallel data 1. Since the alternate patterns of 1, 0 are sent independently of the presence of the output signal from the computer, the continuity of the clock of the receiver is always maintained. |
