VERTICAL DRIVER SIGNAL CONFIGURATION
As shown in Figure 57, XV1 to XV8, XSG1 to XSG6, and
XSUBCK are outputs from the internal AD9925 timing genera-
tor, while V1 to V8 and SUBCK are the resulting outputs from
the AD9925 vertical driver. The vertical driver performs the
mixing of the XV and XSG pulses and amplifies them to the
high voltages required for driving the CCD. Additionally, the
vertical driver outputs are inverted from the internal XV, XSG,
and SUBCK polarities configured by the AD9925 registers.

VERTICAL DRIVER
Table 22 to Table 32 describe the output polarities for these
signals vs. their input levels. Refer to these tables when deter-
mining the register settings for the desired output levels.
Figure 58 to Figure 64 show graphically the relationship between
the polarities of the XV and XSG signals and the inverted verti-
cal driver output signals.
