ABSTRACT:
The present invention is a digital electronics system for generating multiple pulses within a predefined pixel clock period in a digital output device, where both a leading edge delay and a trailing edge delay are specified for a first pulse to be generated during the predetermined clock period. Pulse forming circuitry generates the first pulse during the portion of the clock period between the leading edge delay and the trailing edge delay, and an inverting circuit, selectable on a clock period basis, is activated to produce complimentary pulses within the selected clock period. The system is depicted as a two phase embodiment which enables high-speed operation.
