    摘要: A video controller includes a video block that connects to the print control engine and one laser driver. The video block includes a direct memory access (DMA) block, a video processor, a waveform generator including pattern and multiple pulse mode modulation, a frequency synthesizer, configuration registers, and a data bus. The frequency synthesizer connects to the waveform generator. The configuration registers connect to the DMA block, video processor and the waveform generator. The data bus, operative to carry bus control signals, connects the DMA block, video processor, waveform generator, and the configuration registers.

    摘要: A digital circuit generates very precise varying clock frequencies for applications that can tolerate a small degree of jitter but require exact longer term frequencies, e.g. a video clock for a laser printer. Some subpixel jitter is acceptable, but the overall pixel rate remains exact and consistent. In some applications, the jitter may be desirable to smear the EMI spectrum. For example, if the high frequency input clock is modulated, the edges of the video clock will also be modulated yet remain within the jitter and frequency specification.
