GL646

Genesys Logics single-chip GeneScan™ II , GL646, is a high speed, high performance, low cost and rich scalability controller for scanner. GL646 successfully integrates AFE (16 bits Analog Front End), featuring scanner function ASIC and USB 1.1 interface controller into one single-chip. With its high performance design architecture, GeneScan™ II is not only ready for supporting CIS or CCD image sensors (600dpi or 1200dpi resolution) which are used in flatbed or transparency scanners, but GL646 also is able to co-work with uni-polar or bi-polar stepping motors. Advanced features of GeneScan™ II include 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 GL646 with USB 2.0 and IEEE 1394 interface controller also expand the scalability of GeneScan™ II to fit customers further requirement of supporting high speed interface standards.
