General Description
The LM9812 is a high performance integrated signal proces-
sor/digitizer for color linear CCD image scanners. The LM9812
performs all the signal processing (correlated double sampling,
pixel rate offset and shading correction, color balance control,
and 10-bit analog-to-digital conversion) necessary to maximize
the performance of a wide range of linear CCD sensors.
The LM9812 can be digitally programmed to work with a wide
variety of CCDs from different manufacturers, including both 3
output RGB and 2 output GRGB CCDs. An internal Configura-
tion Register sets CCD and sampling timing to maximize perfor-
mance, simplifying the design and manufacturing processes. For
complementary voltage reference see the LM4041-ADJ.
Applications
Color Flatbed Document Scanners
Color Sheetfed Scanners
Multifunction Imaging Products
Digital Copiers
General Purpose Linear CCD Imaging
Features
6 million pixels/s conversion rate (2MHz/channel x 3)
Pixel rate shading (gain) correction for individual pixels
eliminates errors from PRNU, illumination, etc.
Digitally programmed color balance controls
Pixel rate offset correction for highest quality in dark regions
Correlated Double Sampling for lowest noise
Reference and signal sampling points digitally controlled in
20ns increments
2x and 4x analog fast preview/low resolution modes
Digital control of CCD integration time
Generates all necessary CCD clock signals
Compatible with a wide range of color linear CCDs and
Contact Image Sensors (CIS)
TTL/CMOS input/output compatible
