The LM9833 is a complete USB image scanner system on a single IC. The LM9833 provides all the functions (image sensor control, illumination control, analog front end, pixel processing function image data buffer/DRAM controller, microstepping motor controller, and USB interface) necessary to create a high performance color scanner. The LM9833 scans images in .
• 16 bit ADC digitizes at up to 6Mpixels/s (2M RGB pixels/sec).
• Digital Pixel Processing provides 1200, 800, 600, 400, 300, 200, 150, and 100dpi horizontal resolution from a 1200dpi sensor and 600, 400, 300, 200, 150, 100, 75, and 50dpi horizontal resolution from a 600dpi sensor.
• Provides 50-2400dpi vertical resolution in 1 dpi increments.
• Pixel rate error correction for gain (shading) and offset errors.
• Supports 4 or 16Mbit external DRAMs.
• Multiple CCD clocking rates allows matching of CCD clock to scan resolution and pixel depth for maximum scan speed.
• Stepper motor control tight.
