LM9830 LM9830 36-Bit Color Document Scanner

LM9830 36-Bit Color Document Scanner The LM9830 is a complete 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 .

Features

• Scans at up to 6Mpixels/s (2M RGB pixels/sec).
• Digital Pixel Processing provides 300, 200, 150, 100, 75, and 50 dpi horizontal resolution from 300dpi sensor, and 600, 400, 300, 200, 150, 100, 75, and 50 dpi horizontal resolution from a 600dpi sensor.
• Provides 50-600dpi vertical resolution in 1 dpi increments.
• Pixel rate error correction for gain (shading) and offset errors.
• Output formats include 12 bit linear, 10 bit linear with shading and offset, or 8 bit gamma corrected, all with 12 bit accuracy.
• Multiple CCD clocking rates allows matching of CCD clock to Key Specifications
