60 MHz CCD Signal Processor with V-Driver and Precision Timing Generator ADDI9020 Data Sheet FEATURES GENERAL DESCRIPTION 1.8 V analog/digital core Integrated 12-channel vertical driver (V-driver) 12-bit, 60 MHz analog-to-digital converter (ADC) Complete on-chip timing generator Precision Timing core with ~260 ps resolution Correlated double sampler (CDS) with variable gain 0 dB to 36 dB, 10-bit variable gain amplifier (VGA) Black level clamp with variable level control On-chip 3 V horizontal and reset gate (RG) drivers 2-phase and 4-phase H-clock modes Electronic and mechanical shutter support On-chip 1.8 V LDO On-chip driver for external crystal On-chip sync generator with external sync input 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. APPLICATIONS Packaged in a 7 mm × 7 mm CSP_BGA, the ADDI9020 is specified over an operating temperature range of −25°C to +85°C.
