Abstract
Apparatus, systems, and methods presented herein allow for the alignment of images. In some embodiments, a plurality of PWM modules each receive input data and corresponding input phase-shifted clock signals. In some embodiments, each PWM module generates an output phase-shifted PWM signal based on the input data and its corresponding input phase-shifted clock signal. In some embodiments, a selector selects one of the output phase-shifted PWM signal based on timing relationships between an event signal and the phase-shifted clock signals.
