Figure 15. Timing Diagram for Figure 14
Triple Channel CCD Application
Figure 6 is a block diagram for pixel-by-pixel applica-
tions with triple channel CCDs. During the optically
shielded section of a pixel, CLAMP must go high to
store the black reference on each capacitor to the input.
The gain and offset is automatically rotated to adjust for
each channel input. The MSBs (8 upper bits) are
available on the output bus on the falling edge of
ADCCLK. The LSBs (8 lower bits) are available on the
rising edge of ADCCLK.
Note:
There is an 8 clock latency at the output.
