Abstract
The present invention discloses a system and method for reducing delay difference of differential transmission, a certain delay difference between waveforms of the P signal and N signal is generated through controlling delay adjustment to P signal or N signal of the differential signals and controlling delay adjustment value simultaneously, to compensate for the delay difference of differential transmission due to the channels. Therefore, the present invention can reduce the delay difference of differential transmission due to property discrepancy of board materials and delay inconsistency among pins of the connectors, and at same time simplify the scheme design.
