Preliminary speciﬁcation

I2C-bus controlled TV display processors

TDA933xH series

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

• I2C-bus control of various functions

• Low dissipation.

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.
