Abstract
A method for reducing a clock-data skew in a serial interface. A clock signal and a data signal are received through the serial interface at first and second inputs of an exclusive OR (XOR) averaging (XOR-averaging) gate. An output of the XOR-averaging gate is determined and compared with a target value. At least one of a delay of the clock signal and a delay of the data signal is determined based on comparing the output of the XOR-averaging gate with the target value. A skew between the clock signal and the data signal is reduced by delaying at least one of the clock signal and the data signal.
