DIFFERENTIAL SIGNAL SKEW ADJUSTMENT METHOD AND TRANSMISSION CIRCUIT

摘要

A differential signal skew adjustment method includes: outputting a differential data signal including a first polarity signal and a second polarity signal from a transmission circuit in synchronization with a cycle of a reference clock; adjusting a phase of a detection clock obtained by dividing the reference clock in accordance with a phase of the first polarity signal; and adjusting a phase of the second polarity signal in accordance with an adjusted phase of the detection clock to adjust skew between the first polarity signal and the second polarity signal.
