TDA933xH series
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 (2fH mode) or 15 to 25 kHz (1fH 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.
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
- Low-power start-up option for the horizontal drive circuit
- Vertical count-down circuit
- Vertical driver optimized for DC-coupled vertical output stages
- Vertical and horizontal geometry processing
- Horizontal and vertical zoom possibility and vertical scroll function for application with 16 : 9 picture tubes
- Horizontal parallelogram and bow correction
- I2 C-bus control of various functions
- Low dissipation.
