Linear CCD Sensor Processor
General DescriptionThe LM9811isa high performance integrated signal
processor/digitizerfor linear CCD image scanners. The
LM9811 performsall the analog processing (correlated
double samplingfor black level and offset compensation,
pixel-by-pixel gain (shading) correction, and 10-bit
analog-to-digital conversion) necessaryto maximizetheper-
formanceofa wide rangeof linear CCD sensors.
The LM9811 canbe digitally programmedto work witha
wide varietyof CCDs from different manufacturers.An inter-
nal configuration register sets CCD and sampling timingto
maximize performance, simplifyingthe designand manufac-
turing processes.
The LM9811canbe usedwith parallel output color CCDs.A
signal inversion mode eases use with CIS sensors.For
complementary voltage referenceseethe LM4041.
Applications Colorand Greyscale Flatbedand Sheetfed Scanners Faxand Multifunction Peripherals Digital Copiers General Purpose Linear CCD Imaging
Features1.5 Million pixels/s conversion rate Pixel-rate shading correctionfor individual pixels
maximizes dynamic rangeand resolution, evenon
“weak” pixels Implements Correlated Double Samplingfor minimum
noiseand offset error Referenceand signal sampling points digitally controlled 40ns incrementsfor maximum performance Generatesall necessary CCD clock signals Compatible witha wide rangeof linear CCDs Supports some Contact Image Sensors (CIS) TTL/CMOS input/output compatible
