AD9928

Data Sheet Dual-Channel, 14-Bit CCD Signal Processor with V-Driver and Precision Timing Generator AD9928 FEATURES GENERAL DESCRIPTION 60 MHz grade available (AD9928BBCZ-60) Registers similar to AD9920A and AD9990 Timing generator with 18-channel V-driver Serial data output with reduced range LVDS interface 1.8 V dual AFE core Internal LDO regulators for compatibility with 3 V systems Correlated double sampler (CDS) with −3 dB, 0 dB, +3 dB, and +6 dB gain 6 dB to 42 dB, 10-bit variable gain amplifier (VGA) 14-bit, 40 MHz analog-to-digital converter (ADC) Black level clamp with variable level control Precision Timing core with ~390 ps resolution at 40 MHz On-chip 3 V horizontal and RG drivers General-purpose outputs (GPOs) for shutter support On-chip driver for external crystal 128-ball CSP_BGA package, 9 mm × 9 mm, 0.65 mm pitch APPLICATIONS High speed digital imaging Surveillance cameras Industrial cameras The AD9928 is a highly integrated CCD signal processor for digital still-image camera applications. It includes a dual analog front end with analog-to-digital conversion, combined with a fullfunction, programmable timing generator and an 18-channel vertical driver (V-driver) for a 2-channel output CCD. The timing generator is capable of supporting up to 24 vertical clock signals internally, and the on-chip V-driver supports up to 18 high voltage outputs. A Precision Timing® core allows adjustment of high speed clocks with approximately 390 ps resolution at 40 MHz opera...
