PROBLEM TO BE SOLVED: To provide a DC balanced code generating circuit which generates a DC balanced code for enabling more perfect DC balanced transmission in a configuration simplified rather than a conventional transmission system.;SOLUTION: In a shift register 2, DC balanced data are generated by inverting, in transfer data from a data memory 1 sequentially holding the transfer data for each time slot: data for predetermined bits, e.g., for two bits from a preceding-two-bit data latch circuit 2 holding data for bits from a bit position of a previous time slot retroactive just for two bits; and the transfer data from the data memory 1. The generated DC balanced data are alternately inserted for each bit of the transfer data and a result is outputted as a code serial data output 4. A distance from a positive code output end of a circuit positioned on a front stage of the shift register 2 to a positive code output terminal, to which a pulse transformer or a capacitor is connected, is made equal to a distance from a negative code output end to a negative code output terminal.;COPYRIGHT: (C)2011,JPO&INPIT
