DATA TRANSMISSION CIRCUIT AND A DATA TRANSMISSION METHOD THEREOF, CAPABLE OF CONTROLLING THE DRIVING STRENGTH OF A PRE EMPHASIS

摘要

PURPOSE: A data transmission circuit and a data transmission method thereof are provided to reduce power consumption while using a pre emphasis scheme.;CONSTITUTION: In a data transmission circuit and a data transmission method thereof, a frequency sensor(410) senses an operating frequency. A main driver(420) drives data to an output node. A pre-emphasis driver(430) drives the output node with the pre-emphasis. The pre-emphasis driver controls the strength of the pre-emphasis drive.;COPYRIGHT KIPO 2012
