The LM9830 is a complete document scanner system on a sin-  
gle IC. The LM9830 provides all the functions (CCD control, illu-  
mination control, analog front end, pixel processing function  
image data buffer/SRAM controller, microstepping motor control-  
ler, and EPP parallel port interface) necessary to create a high  
performance color scanner. The LM9830 scans images in 36 bit  
color, and has output data formats for 36 bits, 30 bits, and 24  
bits.  
LM9830 36-Bit Color Document Scanner  
scan resolution and pixel depth for maximum scan speed.  
Stepper motor control tightly coupled with buffer management  
to maximize data transfer efficiency.  
PWM stepper motor current control allows microstepping for  
the price of fullstepping.  
General Description  
•
•
•
•
Supports 64k, 128k, or 256k x8 external SRAMs.  
Parallel Port interface supports EPP, PS2 (bidirectional), or  
SPP (nibble) modes of operation.  
•
Pixel depths of 1, 2, or 4 bits are packed into bytes for faster  
scans of line art and low pixel depth images.  
Supports 1 and 3 channel CIS and CCD devices.  
3 (R, G, and B) user-programmable gamma correction tables.  
Able to transmit an arbitrary range of pixels to speed up  
scanning of smaller items (business cards, etc.) by zooming  
in on a subset of CCD pixels.  
•
•
•
The only additional active components required are an external  
SRAM for data buffering and power transistors for the stepper  
motor. Parallel port pass-through requires two additional  
TTL/CMOS logic ICs.  
Applications  
•
Compatible with a wide range of color linear CCDs and  
Contact Image Sensors (CIS)  
Internal bandgap voltage reference.  
• Color Flatbed Document Scanners  
• Color Sheetfed Document Scanners

300, 200, 150, 100, 75, and 50 dpi horizontal resolution from  
a 600dpi sensor.  
• A4 Color 150dpi scan (typical, EPP Interface) <10 seconds  
• A4 Color 300dpi scan (typical, EPP Interface) <40 seconds  
• A4 Color 600dpi scan (typical, EPP Interface) <160 seconds
