Description

Genesys Logic's single-chip GeneScanTMII, GL646USB, is a high speed, high performance, low cost and rich calabilitycontroller for scanner. GL646USB 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 GL646USB also can co-work with uni-polar or bi-polar stepping motors. Advanced features of eneScanTMII 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 of GL646USB also expand the scalability of GeneScan TMII to fit customer's further requirement of supporting high speed interfacestandards.
