Abstract
An interface driver circuit includes a plurality of delay cells. Each delay cell includes a data input, a delayed data output configured to communicate with the data input of an adjacent one of the plurality of delay cells. A delay time input is configured to set a delay value between receiving data at the data input and generating the delayed data output. A plurality of predrivers is configured to receive an output enable signal. A plurality of predrivers is configured to receive a corresponding one of the plurality of delayed data outputs. A plurality of predrivers is configured to generate a predriver output signal based on the output enable signal and the corresponding one of the plurality of delayed data outputs. The output enable signal enables and disables the plurality of predrivers and is independent of data of each delayed data output.
