GENERAL DESCRIPTION
The TDA9160 is an I
controlled, alignment-free
PAL/NTSC/SECAM
decoder/processor. The device
contains horizontal and vertical drive
outputs and an east-west correction
drive circuit. The TDA9160 has been
designed for use with baseband
chrominance delay lines and
DC-coupled vertical and east-west
output circuits.
The device has three inputs, two for
CVBS and one for S-VHS. The main
signal is available at the luminance
and colour difference outputs and,
also, at the TXT output
(unprocessed). The signal at the PIP
output can be selected independently
from the main signal.
The circuit provides a drive pulse for
the horizontal output stage, a
differential sawtooth current for the
vertical output stage and an east-west

drive current for the EW output stage.
These signals can be used to provide
geometry correction of the picture. A
two level sandcastle pulse and an H
pulse are made available for
synchronization purposes
.The I
can be programmed by hardware.
