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 circuithasvariousfeaturesthatareattractiveforthe
application of 16 : 9 picture tubes.
Thecircuitcanbeused in bothsinglescan(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.
