IT 9943 -
Complete 10-Bit, 25MHz CCD Signal Processor
Description
The IT9943 are complete analog signal processors for CCD applications. It feature a 25MHz single-channel architecture designed to sample and condition the outputs of interlaced and progressive scan area CCD arrays. The signal chain for the IT9943 consists of a correlated double sampler (CDS), a digitally controlled variable gain amplifier (VGA), and a black level clamp. The IT9943 offers 10-bit ADC resolution.
The internal registers are programmed through 3-wire serial digital interface. Programmable features include gain adjustment, black level adjustment, input clock polarity, and power-down modes. The IT9943 operate from a single 3V power supply, typically dissipate 79mW, and are package in space-saving 32-lead QFN packages.
