Data Sheet
AD9943/AD9944
APPLICATIONS INFORMATION
products for digital still camera and camcorder applications. As
shown in Figure 12, the CCD image (pixel) data is buffered and
restoration, CDS, gain adjustment, black level correction, and
output data is then processed by the image processing ASIC.
The internal registers of the AD9943/AD9944—used to control
gain, offset level, and other functions—are programmed by the
ASIC or microprocessor through a 3-wire serial digital
interface. A system timing generator provides the clock signals
for both the CCD and the AFE.
