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 TDA933xH 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 (2fH mode) or 15 to 25 kHz (1fH mode), so that the TDA933xHs can also be used to display SVGA signals.

The supply voltage of the ICs is 8 V. TDA933xH are each contained in a 44-pin QFP package.
