AD9943/AD9944
APPLICATIONS INFORMATION
The AD9943/AD9944 are complete analog front end (AFE)
products for digital still camera and camcorder applications. As
shown in Figure 12, the CCD image (pixel) data is buffered and
sent to the AD9943/AD9944 analog input through a series input
capacitor. The AD9943/AD9944 perform the dc restoration,
CDS, gain adjustment, black level correction, and analog-to-
digital conversion. The AD9943/AD9944’s digital 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.
