Abstract: The lane skew alignment device of the present invention facilitates the use of the SFI-5 standard interface in an FPGA without the need to rely on feedback signals from a remote device. The delay between lanes is determined using a D-Flip Flop or other type of phase comparator. To minimize the components needed to physically implement the solution a cross-point switch is used to select one of the parallel lanes at a time to be compared to a reference lane, over which the same test signal is transmitted.
