DESCRIPTION
Input Phase:
The VSP1900 is a CCD vertical clock driver with electric-
shutter support. This device is composed of eight vertical
transfer channels, which support both 3-field CCD and
2-field CCD operation. The VSP1900 contributes low
power consumption and parts number reduction in the
system.

DESCRIPTION
The VSP1900 is a CCD vertical clock driver with electric shutter. The VSP1900 is composed of five 3-state and three
2-state vertical transfer channels, which support both 3 field and 2 field CCD operation. The VSP1900 contributes
low power consumption and parts number reduction in the system.
OPERATION
Power On/Off Sequence
This is the same as the CCD power up sequence, when power on, VDD powers on first VH, VM power on second,
and VL powers on later. When powering off, VL powers off first, VH, VM power of second, and VDD powers off later.
Vertical Transfer Signal
The VSP1900 receives signals from TG (CCD timing generator). The input signal is converted into CCD operation
voltage level by the level shifter. The level shifter circuits connect to a 2-state or 3-state driver, which is connected
to the CCD input pin. While using a 2-field CCD, one of the 3-state drivers is used as a 2-state driver. The CH#N pin
is pulled up internally, so that the VH level does not appear on the output pin.
