LM9833 - LM9833 48-Bit Color / 1200dpi USB Image Scanner

Description

The LM9833 is a complete USB image scanner system on a single IC.

Features

  • 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.

LM9833 48-Bit Color 1200dpi USB Image Scanner October 2001 LM9833 48-Bit Color, 1200dpi USB Image Scanner General Description 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 48 bit color/16 bit gray, and has output data formats for 48 and 24bit color/16 and 8 bit gray. The LM9833 supports sensors with pixel counts of up to 16384 pixels x 3 colors (1200 dpi x 13.6 inches). The LM9833’s low operating and suspend mode supply currents allow design of USB bus-powered scanners.
