GL646USB
1. GENERAL DESCRIPTION
Genesys Logic's single-chip GeneScanTMII, GL646USB, is a high speed, high performance, low cost and rich scalability
controller for scanner. It successfully integrates AFE (16 bits Analog Front End), featured scanner function ASIC and
USB 1.1 interface controller into one single-chip. With it’s high performance design architecture, GeneScanTMII is not
only ready for supporting CIS or CCD image sensors (600dpi or 1200dpi resolution) which is used in flatbed or
transparency scanners, but also can co-work with uni-polar or bi-polar stepping motors. Advanced features of
GeneScanTMII includes loseless image data compression, dual motor acceleration/ deceleration curve table for high speed
motor moving, industrial standard auto suspend mode and bus-power supporting.
Except the build-in USB 1.1 interface, the capability of cooperating with USB 2.0 and IEEE 1394 interface controller
also expand the scalability of GeneScan TMII to fit customer's further requirement of supporting high speed interface
standards.
2. FEATURES

CCD : Chunky color or planar color.
CIS : Planar color
6.3. Scan Speed
A. System clock = 24 MHz :
a. Normal Mode: Chunky color or fine gray scan.
24x41.666ns/pixel = 1.0us/pixel
(1). 600dpi : 5.4ms/line
(2). 1200dpi : 10.4ms/line
b. Fast Mode: Planar color, fast gray or black&white scan.
9x41.666ns/pixel = 0.375us/pixel
12x41.666ns/pixel = 0.5us/pixel
15x41.666ns/pixel = 0.625us/pixel
(1). 600dpi : 2.025~3.375ms/line
(2). 1200dpi : 4.05~6.75ms/line
B. System clock = 32MHz :
a. Normal Mode :
24x31.25ns/pixel = 0.75us/pixel
(1). 600dpi : 4.05ms/line
(2). 1200dpi : 8.1ms/line
b. Fast Mode :
9x31.25ns/pixel = 0.281us/pixel
12x31.25ns/pixel = 0.375us/pixel
Rev. 1.4
-12-
GL646USB
15x31.25ns/pixel = 0.469us/pixel
(1). 600dpi : 1.517~2.533ms/line
(2). 1200dpi : 3.034~5.066ms/line
6.4. Fast scan for low DPI
Multiple CCD clocking rates allows speed up scan speed. You can speed up 2 times, 3 times or 4 times scanning
time for low resolution.
For example,600dpi scanner: if 75dpi speed up 4 times then 5.4ms/4=1.35ms/line. Scan speed is equal to 1.18s/page.
Chunky scan: You can speed up 2 times,3 times or 4 times scanning time.
Planar scan: 9 system clock/pixel: You can not speed up scanning time
12 system clock/pixel : You can speed up 2 times scanning time
15 system clock/pixel : You can speed up 2 times scanning time
6.5. Scanning Type
Support three line in(parallel ) for CCD, one line in for CCD or CIS, RGB line by turns in for CCD three types.

6.6. Image Sensor Timing
Can be programmed.
A. CCD : support 600,1200 or 2400 dpi CCD.
For example NEC, TOSHIBA, Sony ……etc.
B. CIS : support 600,1200 or 2400 dpi CIS.
For example Canon , Toshiba , Mitsubishi ……etc.
6.7. Dummy Line
Support programmable dummy lines to resolve (overcome) Start/Stop problem.
You can insert dummy lines to reduce scanner stop and wait events (buffer full) or always no-stop.
A. Line base of dummy lines:
The range of dummy lines is 0 line ~ 15 lines.
B. Adjustable dummy line:
The range is CCD or CIS minimum shift out time to 512k pixels time, can be adjusted by 1 pixel time increment.
6.8. Analog Front End Timing :
Internal 16 bits Front-End : Operation is similar to Wolfson or Analog Device.
6.9. Image Type
Support color, fine gray, fast gray and fast Black & White scan.
Support color filters selection for gray and B/W scan. The filters include Red, Green and Blue.
Note: The scan style of fine gray and color is same. So, fine gray scanning speed is slow.
The exposure time of fast gray scan is shorter than fine gray scan. So, fast gray Scanning speed is high.
6.10. Bits Depth
16 x3 Bits true color , 16 bits gray level and one bit Black & White.
Image data type : 16 bits , 8 bits and 1 bit data type.
6.11. Shading & Correction
a. White Shading & Dark Shading:
Rev. 1.4
-14-
GL646USB
Internal white shading by pixel (16 bits resolution) and dark shading by pixel (16 bits resolution) can be enabled or
disabled By S/W. The white shading curve is calculated by S/W.
Data arrangement: Normal mode: dark R1,white R1,dark G1,white G1,dark B1,white B1,
dark R2,white R2,dark G2,white G2,dark B2,white B2,
dark R3,white R3,dark G3,white G3,dark B3,white B3,……
Fast mode: dark R1,white data R1,dark R2,white R2,dark R3, white R3…
dark G1,white data G1,dark G2,white G2,dark G3,white G3…
dark B1,white data B1,dark B2,white B2,dark B3,white B3…
White shading formula :
2000H x Target / (Wn-Dn) = White Gain data ----- for 8 times system
White shading formula :
4000H x Target / (Wn-Dn) = White Gain data ----- for 4 times system
For example : Target = 3FFFH
then
Wn = 2FFFH
Dn = 0040H
and 8 times system operation
White Gain = 2000H x 3FFFH / (2FFFH-0040H) = 2AE4H (1.34033 times)
b. Correction :
GAMMA correction table by S/W calculation. The resolution is 12 or 14 bits gamma table.
Range: 0 to 64k (16 bits) input mapping to 0 to 4k (12 bits) output ;
0 to 64k (16 bits) input mapping to 0 to 16k (14 bits)output;
0 to 64k (16 bits) input mapping to 0 to 255 (8 bits) output ;
0 to 64k (16 bits) input mapping to 0 to 255 (8 bits) output;
6.12. Threshold Level Setting
Can be programmed by S/W.
Range: 0 to 255 can be adjusted by one increment.

-16-
GL646USB
The resolution of motor speed control is 16 bits, so, we can control vertical resolution
By one dpi increment, the resolution can be from 1 DPI to 4800DPI for 1200DPI scanner
And 1 DPI to 9600 DPI for 2400dpi scanner.
Note: The resolution of quarter step can up to four times resolution.
6.20. Acceleration/Deceleration Double Table
The acceleration/deceleration slope tables are store in DRAM, can be download by S/W.
The slope can be programmed by S/W for each table. Resolution is 16 bits pixel-time. The number of slope steps is
1~255 steps. One table is for scanning The other is for fast move.
The forward and backward steps can be programmed by S/W. The resolution is 16 bits pixel-time. The number of
slope steps is 1~255 steps. You can adjust any non-linear curve.
Note: what is fast move? Such as move back to go home or move to window any position to scan.
