APPLICATIONS

High speed digital cameras GENERAL DESCRIPTION The ADDI9020 is a complete 60 MHz front-end solution for digital still cameras and other charge-coupled device (CCD) imaging applications. The ADDI9020 includes the analog front end (AFE), a fully programmable timing generator (TG), and a 12-channel V-driver. A Precision Timing® core allows adjustment of high speed clocks with approximately 260 ps resolution at 60 MHz operation. The on-chip V-driver supports up to 12 channels for use with multifield CCDs. The analog front end includes black level clamping, CDS, VGA, and a 12-bit ADC. The timing generator and V-driver provide all the necessary CCD clocks: RG, H-clocks, vertical clocks, sensor gate pulses, a substrate clock, and substrate bias control. The internal registers are programmed using a 3-wire serial interface. over an operating temperature range of −25°C to +85°C. FUNCTIONAL BLOCK DIAGRAM Figure 1.
