GENERAL DESCRIPTION
The TDA933xH series are display processors for
`High-end' television receivers which contain the following
functions:
RGB control processor with Y, U and V inputs, a linear
RGB input for SCART or VGA signals with fast blanking,
a linear RGB input for OSD and text signals with a fast
blanking or blending option and an RGB output stage
with black current stabilization, which is realized with the
CCC (2-point black current measurement) system.
Programmable deflection processor with internal clock
generation, which generates the drive signals for the
horizontal, East-West (E-W) and vertical deflection.
The circuit has various features that are attractive for the
application of 16 : 9 picture tubes.
The circuit can be used in both single scan (50 or 60 Hz)
and double scan (100 or 120 Hz) applications.
In addition to these functions, the TDA9331H and
TDA9332H have a multi-sync function for the horizontal
PLL, with a frequency range from 30 to 50 kHz (2f
H
mode)
or 15 to 25 kHz (1f
H
mode), so that the ICs can also be
used to display SVGA signals.
The supply voltage of the ICs is 8 V. They are each
contained in a 44-pin QFP package.
