AD9937
SYSTEM OVERVIEW
Figure 8 shows the typical system block diagram for the AD9937.
The CCD output is processed by the AD9937
s AFE circuitry,
which consists of a CDS, VGA, black level clamp, and A/D
converter. The digitized pixel information is sent to the digital
image processor chip, which performs the postprocessing and
compression. To operate the CCD, all CCD timing parameters
are programmed into the AD9937 from the system micropro-
cessor, through the 3-wire serial interface. From the system
master clock, VCKM provided by the image processor or exter-
nal crystal, the AD9937 generates all of the CCD
s horizontal
and vertical clocks and all internal AFE clocks.

The H-drivers for H1(A
D) and H2(A,B), and RS are included
in the AD9937, allowing these clocks to be directly connected
to the CCD. H-drive voltage of up to 3.6 V is supported. An
external V-driver is required for the vertical transfer clocks and
sensor gate pulses.
Figure 9 shows the horizontal and vertical counter dimensions
for the AD9937. All internal horizontal and vertical clocking is
programmed using these dimensions to specify line and pixel
locations.
