Abstract

Data clocking circuitry providing data clocking signals usable to control the output of a laser directed to a self-resonant mirror of a scanning apparatus. The circuitry selects clock signals from the output of a stable clock in accordance with a program stored in a memory and with the output of a voltage controlled oscillator (VCO) used to provide the data clocking signals with the VCO provided with a control signal based on the difference in the accumulated count between the selected clock signals and data clocking signals.
