ABSTRACT:
A circuit for data alignment includes a first latch unit and a second latch unit. The first latch unit latches serial input data by using a plurality of first clocks with different phases and the same frequency to output latched data. The second latch unit latches the data from the first latch unit by using a plurality of second clocks with a lower frequency than the first clocks and more diverse phases to thereby output parallel data.
