A write data precompensator system is described which comprises a delay element circuit (12) which receives a clock signal and outputs a delayed clock signal which includes a programmable selectable delay in the rising edge of the clock signal. The amount of delay is received using a delay voltage level generated by a delay level circuit (16) which receives delay magnitude control values in digital form. A reference level circuit (18) also generates a continuous level voltage level so that the delay element circuit (12) can instantly change between a delayed operation and an undelayed operation without waiting for the delay voltage level to adjust.
