Abstract
PURPOSE: To perform the conversion operation surely according to the conversion rule, by preventing inversion of the logical value of the bit in the last bit by the suppress signal corresponding to the last bit indicating one logical value in a prescribed sequence.
CONSTITUTION: In respect to data signal DT output from data signal generator DTG on a basis of two-phase clock signals ϕ1 and ϕ2 from clock signal generator CKG, conversion to the M2 code is performed by encoding circuit ENC. The inversion operation in the bit boundary in the encoding operation, the inversion operation in the bit boundary, and the inversion operation control in the bit center are performed independently of one another at the timing of each fall of two-phase clock signals ϕ1 and ϕ2 which have phases shifted by 180°. Thus, AND output signal Gs from AND gate circuit 9, namely, the suppress signal is used to suppress the inversion operation in the bit center corresponding to the last bit of the sequence, and the conversion operation to the M2 code is performed accurately in respect to data signal DT.
