Part Details:

a Complete 10-Bit 20 MSPS CCD Signal Processor AD9843A FEATURES PRODUCT DESCRIPTION 20 MSPS Correlated Double Sampler (CDS) The AD9843A is a complete analog signal processor for CCD 4 dB 6 dB Variable CDS Gain with 6-Bit Resolution applications. It features a 20 MHz single-channel architecture 2 dB to 36 dB 10-Bit Variable Gain Amplifier (VGA) designed to sample and condition the outputs of interlaced and Low Noise Clamp Circuits progressive scan area CCD arrays. The AD9843A s signal chain Analog Preblanking Function consists of an input clamp, correlated double sampler (CDS), 10-Bit 20 MSPS A/D Converter digitally controlled variable gain amplifier (VGA), black level Auxiliary Inputs with VGA and Input Clamp clamp, and 10-bit A/D converter. Additional input modes are 3-Wire Serial Digital Interface provided for processing analog video signals. 3 V Single Supply Operation The internal registers are programmed through a 3-wire serial Low Power: 65 mW @ 2.7 V Supply digital interface. Programmable features include gain adjust- 48-Lead LQFP Package ment, black level adjustment, input configuration, and power- APPLICATIONS down modes. Digital Still Cameras The AD9843A operates from a single 3 V power supply, typi- Digital Video Camcorders cally dissipates 78 mW, and is packaged in a 48-lead LQFP.
