LM9812 30-Bit Color Linear CCD Sensor Processor  
General Description  
Features  
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.  
• 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)  
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.  
• TTL/CMOS input/output compatible
