Figure 1. Typical Application
Figure 1 shows the typical system application diagram for the
AD9948. The CCD output is processed by the AD9948’s AFE
circuitry, which consists of a CDS, a PxGA, a VGA, a black level
clamp, and an A/D converter. The digitized pixel information is
sent to the digital image processor chip, where all postprocessing
and compression occurs. To operate the CCD, CCD timing
parameters are programmed into the AD9948 from the image
processor through the 3-wire serial interface. From the system
master clock, CLI, provided by the image processor, the AD9948
generates the high speed CCD clocks and all internal AFE clocks.
All AD9948 clocks are synchronized with VD and HD. All of
the AD9948’s horizontal pulses (CLPOB, PBLK, and HBLK)
are programmed and generated internally.
The H-drivers for H1–H4 and RG are included in the AD9948,
allowing these clocks to be connected directly to the CCD.
H-drive voltage of 3 V is supported in the AD9948.
Figure 2a shows the horizontal and vertical counter dimensions
for the AD9948. All internal horizontal clocking is programmed
using these dimensions to specify line and pixel locations.
