Overview
Data Sheet FEATURES Pin-compatible upgrade for the AD9945 45 MHz correlated double sampler (CDS) with variable gain 6 dB to 42 dB, 10-bit variable gain amplifier (VGA) Low noise optical black clamp circuit Preblanking function 12-bit, 45 MHz ADC No missing codes guaranteed 3-wire serial digital interface 3 V single-supply operation Space-saving, 32-lead, 5 mm × 5 mm LFCSP APPLICATIONS Digital still cameras Digital video camcorders PC cameras Portable CCD imaging devices CCTV cameras Complete, 12-Bit, 45 MHz CCD Signal Processor ADDI7100 GENERAL DESCRIPTION The ADDI7100 is a complete analog signal processor for chargecoupled device (CCD) applications.
It features a 45 MHz, single-channel architecture designed to sample and condition the outputs of interlaced and progressive scan area CCD arrays.
The signal chain for the ADDI7100 consists of a correlated double sampler (CDS), a digitally controlled variable gain amplifier (VGA), a black level clamp, and a 12-bit ADC.
The internal registers are programmed through a 3-wire serial digital interface.
Programmable features include gain adjustment, black level adjustment, input clock polarity, and power-down modes.
The ADDI7100 operates from a single 3 V power supply, typically dissipates 125 mW, and is packaged in a space-saving, 32-lead LFCSP.
