revision 1.3 mar.22 2001 -2- GL646USB 1. general description genesys logic's single-chip genescan tm ii, 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, genescan tm ii 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 genescan tm ii 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 tm ii to fit customer's further requirement of supporting high speed interface standards. 2. features design for sheetfed, flatbed and transparency scanner. programmable 600,1200 or 2400 dpi color ccd or cis timing support fast scan for low dpi such as pre-view support three scanning type :pixel by pixel(pixel rate), line by line(line rate) and rgb line by turns(line rate) programmable dummy lines to resolve start/stop (discontinuous) problem. 48-bits true color ( 16-bits gray level ) scan support color , fine gray , fast gray and fast b/w scan for ccd support color , gray , true gray and b/w scan for cis built-in 16 bits front end 16 bits white shading , dark shading and 12/14 bits gamma correction programming threshold level for b/w exposure time is adjustable (max.524ms , 1 pixel time increment step) scan width(scan area) control for horizontal line( 1 pixel increment step) built-in usb(1.1) , external usb(2.0) and external ieee1394 interface support 4m bits x 1 or x2 (256k x 16) edo dram support digital average for dpi (non-deletion type) support hardware deletion type for dpi (2400 to 1 dpi ,1 dpi decrement) acceleration/ deceleration double table for high speed motor moving stepping motor phase control ports for bi-polar or uni-polar motor full, half and quarter steps for motor control build-in uni-polar phase pwm control watch-dog protection circuit for motor, lamp and asic system 2 output ports for lamp (include flatbed and transparency with pwm) control input port for home sensor 9 gpio ports lamp timeout (sleeping) control
