Abstract
An encoding circuit with a function of zero continuous-suppression in a data transmission system according to the present invention includes an EXZ detecting unit, a NRZ pulse generating unit and an output control unit. The EXZ detecting unit receives serial data indicating a NRZ signal and binary information indicating a code rule, and outputs EXZ pulses and delay data. The NRZ pulse generating unit receives the EXZ pulses from the EXZ detecting unit, and outputs an EXZ detecting signal, bipolar rule pulses and violation pulses. The output control unit receives the EXZ detecting signal, the bipolar rule pulses and the violation pulses, these are output from the NRZ pulse generating unit, and the delay data from the EXZ detecting unit, and outputs P-pole pulses and N-pole pulses to an external stage, and an odd signal to the NRZ pulse generating unit.
