LM9830 36-Bit Color Document Scanner November 1998 General Description LM9830 36-Bit Color Document Scanner The LM9830 is a plete document scanner system on a single IC. The LM9830 provides all the functions (CCD control, illumination control, analog front end, pixel processing function image data buffer/SRAM controller, microstepping motor controller, and EPP parallel port interface) necessary to create a high performance color scanner. The LM9830 scans images in 36 bit color, and has output data formats for 36 bits, 30 bits, and 24 bits. The only additional active ponents required are an external SRAM for data buffering and power transistors for the stepper motor. Parallel...
