APPLICATIONS INFORMATION
The ADDI7100 is a complete analog front-end (AFE) product
for digital still camera and camcorder applications. As shown in
Figure 14, the CCD image (pixel) data is buffered and sent to
the ADDI7100 analog input through a series input capacitor.
The ADDI7100 performs the dc restoration, CDS sampling,
gain adjustment, black level correction, and analog-to-digital
conversion. The digital output data of the ADDI7100 is then
processed by the image processing ASIC. The internal registers
of the ADDI7100—used to control gain, offset level, and other
functions—are programmed by the ASIC or by a microprocessor
through a 3-wire serial digital interface. A system timing generator
provides the clock signals for both the CCD and the AFE (see
