Abstract
Embodiments of the present invention provide for generating a sampled differential pattern signal with reduced jitter. In one embodiment of the present invention, a seed frequency generator provides a differential seed frequency signal. The differential seed frequency signal is converted to a single ended seed frequency signal by a differential-to-single ended converter. The pattern generation logic utilizes the single ended seed frequency signal to generate single ended pattern signals. Single ended-to-differential samplers then generate a sampled differential pattern signal by sampling the single ended pattern signal according to the differential seed frequency signal.
