描述 Description

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.FEATURES
Available in all ICs:
? Can be used in both single scan (50 or 60 Hz) and double scan (100 or 120 Hz) applications
? YUV input and linear RGB input with fast blanking
? Separate OSD/text input with fast blanking or blending
? Black stretching of non-standard luminance signals
? Switchable matrix for the colour difference signals
? RGB control circuit with Continuous Cathode Calibration (CCC), plus white point and black level offset adjustment
? Blue stretch circuit which offsets colours near white towards blue
? Internal clock generation for the deflection processing, which is synchronized by a 12 MHz ceramic resonator oscillator
? Horizontal synchronization with two control loops and alignment-free horizontal oscillator
? Slow start and slow stop of the horizontal drive pulses
