12-Bit CCD Signal Processor with V-Driver and Precision Timing Generator AD9920A FEATURES GENERAL DESCRIPTION Integrated 19-channel V-driver The AD9920A is a highly integrated charge-coupled device (CCD) 1.8 V AFETG core signal processor for digital still camera applications. It includes a 24 programmable vertical clock signals complete analog front end (AFE) with analog-to-digital conversion, Correlated double sampler (CDS) with -3 dB, 0 dB, combined with a full-function programmable timing generator +3 dB, and +6 dB gain and 19-channel vertical driver (V-driver). The timing generator 12-bit, 40.5 MHz analog-to-digital converter (ADC) is capable of supporting up to 26 vertical clock signals to control Black level clamp with variable level control advanced CCDs. The on-chip V-driver supports up to 19 channels Complete on-chip timing generator for use with 6-field CCDs. A Precision TimingTM core allows adjust- Precision Timing core with ~400 ps resolution ment of high speed clocks with approximately 400 ps resolution On-chip 3 V horizontal and RG drivers at 40.5 MHz operation. The AD9920A also contains six GPOs General-purpose outputs (GPOs) for shutter and that can be used for shutter and system functions. system support The analog front end includes black level clamping, variable On-chip sync generator with external sync input gain CDS, and a 12-bit ADC. The timing generator provides all On-chip 1.8 V low dropout (LDO) the necessary CCD clocks: RG, H-clocks, V-clocks, sensor gate 105-lead 8 mm × 8 mm CSP_BGA package pulses, substrate clock, and substrate bias control. APPLICATIONS The AD9920A is specified over an operating temperature range Digital still cameras of -25°C to +85°C.
