A feed forward equalizer for analog equalization of a data signal received over a data transmission channel comprising a Master Delay Locked Loop (MDLL) for generating equidistant reference phase signals; a Slave Delay Line (SDL) formed by serial connected Slave Delay Units (SDU), wherein each Slave Delay Unit (SDU) has a Slave Delay Element (SDE) to delay the received data signal with a predetermined delay time (DeltaT) and an analog amplifier which amplifies the delayed output signal of the Slave Delay Element (SDE) with a respective weighting coefficient to generate a weighted delay signal, wherein the analog amplifier is switched transparent in response to a corresponding reference phase signal generated by said Master Delay Locked Loop (M-DLL); and subtracting means for subtracting the weighted delay signals which are selected by means of a multiplexer from the received data signal to generate an equalized output data signal.
