DIFFERENTIAL TYPE TRANSMISSION APPARATUS

摘要

PPROBLEM TO BE SOLVED: To provide a data collision detecting method certainly detecting data collision irrespective of a simple configuration. PSOLUTION: A mismatched signal is produced even if no collision occurs between transmission data and reception data, and a pulse width of the mismatched signal at the time when data collision occurs is long while the pulse width of the mismatched signal at the time when no data collision occurs is short. A differential type transmission apparatus is equipped with: a differential type line driver for transmitting a transmission data signal toward a transmission path; a differential type line receiver for receiving a reception data signal transmitted from the transmission path; a signal comparing unit for producing a mismatched signal after comparing a wave form of the transmission data signal with a waveform of the reception data signal; and a determining unit for determining collision on the transmission path between the transmission data and the reception data based on a pulse width x1 of the mismatched signal transferred from the signal comparing unit.
