CS7615  
CCD Imager Analog Processor  
Features  
Description  
The CS7615 is a low-power Analog front-end processor  
for standard four-color interline transfer CCD imagers.  
The architecture includes a correlated double sampler,  
AGC amplifier, black-level clamp, 10-Bit A/D converter,  
and a complete multi-sync CCD timing generator. The  
analog CCD imager output can be directly connected to  
the CS7615 input, which does not require an external  
buffer amplifier. The pixel data is double sampled for im-  
proved noise performance, and gain adjusted prior to  
being digitized by the A/D converter. Feedback from the  
A/D converter holds the image black level at code-16  
(assumes 8-bit data path), addressing ITU-601 compli-  
ance issues. The multi-sync CCD timing generator is

programmed via the I C bus, and can be used with a  
wide range of interline transfer CCD imagers up to 1000  
pixels wide. The CS7615 supports full ITU-601 compli-  
ance for images up to 720 pixels wide, and is compatible  
with both NTSC and PAL timing. The CS7615 is de-  
signed to be used along with either the CS7665 or  
CS7666 Digital Color-Space Processor for CCD Camer-  
as, which generates a 4:2:2 component digital video  
output.
