ABSTRACT:
A method of achieving line-to-line synchronization having a high degree of synchronization accuracy. Synchronization is performed by a specific high-speed block of logic which signals the beginning of scans to a PELCLK-based logic at pel boundaries, and provides sub-pel shifting as it passes data between the pel generation logic and a laser control signal. The synchronization error is made as small as propagation delays through a single multiplexer element. Such delays can be controlled to values less than 1/2 ns. The need to stop and restart the clocks is eliminated. All complex pel generation logic is clocked with the relatively low frequency PELCLK without regard to the synchronization task.
