CCD Signal Processor  
a
AD9840A  
PRODUCT DESCRIPTION  
FEATURES  
The AD9840A is a complete analog signal processor for CCD  
applications. It features a 40 MHz single-channel architecture  
designed to sample and condition the outputs of interlaced and  
progressive scan area CCD arrays. The AD9840A’s signal chain  
consists of an input clamp, correlated double sampler (CDS),  
digitally controlled variable gain amplifier (VGA), black level  
clamp, and 10-bit A/D converter. Additional input modes are  
provided for processing analog video signals.  
40 MSPS Correlated Double Sampler (CDS)  
4 dB 6 dB Variable CDS Gain with 6-Bit Resolution  
2 dB to 36 dB 10-Bit Variable Gain Amplifier (VGA)  
Low Noise Clamp Circuits  
Analog Preblanking Function  
10-Bit 40 MSPS A/D Converter  
Auxiliary Inputs with VGA and Input Clamp  
3-Wire Serial Digital Interface  
3 V Single Supply Operation  
Low Power: 155 mW @ 3.0 V Supply  
48-Lead LQFP Package  
The internal registers are programmed through a 3-wire serial  
digital interface. Programmable features include gain adjustment,  
black level adjustment, input configuration, and power-down modes.  
APPLICATIONS  
The AD9840A operates from a 3 V power supply, typically  
dissipates 155 mW, and is packaged in a 48-lead LQFP.
