GT-6816

I. General Descriptions- w w w t e efor high-performance color scanner. The GT-6816 is enhanced not only in the AFE (SOC) solution h (Analog S Front End) from 12-bit to 16-bit but also built-in an intelligent power management circuit to a meettboth operating and suspend mode for USB bus-powered Scanner. The GT-6816 is also pin to pin a backward compatible with the GT-6801, providing system designer easy way to upgrade the current D . applications without changing the hardware design. II.
