Abstract
A system and method are used to allow for phase rotator control signals to be produced that rotate bits in the signals more than one step per clock cycle. This can be done through the following operation. First and second data signals that include a plurality of data bits are stored. Rotation of data bits in the first data signal and subsequently data bits in the second data signal is controlled based on a phase control signal during each clock cycle. The first and second controlled data signals are interleaved to form first and second interleaved data signals. One of the first and second interleaved data signals is selected based on a portion of the phase control signal during a second half of the clock cycle. Finally, the selected data signal is transmitted as the phase control signal.
