PURPOSE: An interface of a low voltage differential signaling method is provided to improve the property of an output frequency by compensating the operation speed of the whole differential amplifier even though any one of differential amplifiers is not operated. CONSTITUTION: A first amplifier(AMP1) and a second amplifier(AMP2) amplify a low differential voltage from a low voltage differential input terminal(INP) and a high differential voltage from a high voltage differential input terminal(INN). A common voltage generator(CG) generates a common voltage by using the high differential voltage and the low differential voltage. A first operation speed compensator(DC1) receives a limit value of the operable input voltage of the first differential amplifier as a first reference voltage. A first operation speed compensator determines whether to supply a first driving voltage to the second differential amplifier. A second operation speed compensator(DC2) determines whether to supply a second driving voltage to the first differential amplifier. |
