The design and operation of a new high speed family of CCD line imaging devices are pre-sented in this paper. The devices, CCD 133 and CCD 143, contain 1024 and 2048 photosites on 13 μm centers respectively. They are second generation devices having an overall improved performance compared with the first generation devices (CCD 121 and CCD 131) including higher sensitivity, enhanced blue response and lower dark signal. The devices also incorpo-rate on-chip clock driver circuitry so that only two external clocks are required for their operation. Excellent performance has been obtained with up to 20 MHz data rate. The devices are designed for page scanning applications including high speed facsimile, optical character recognition, and other imaging systems which require high resolution, high sensitivity, and high speed.
