Product specification

TDA8433

FEATURES

• I2C-bus interface

• Input for vertical sync

• Sawtooth generator with amplitude

independent of frequency

• Vertical deflection output stage

driver

• East-west raster correction drive

output

• EHT modulation input

• Changes picture width and height

without affecting geometry.

GENERAL DESCRIPTION

The TDA8433 is an I2C-bus

controlled deflection processor which,

together with a sync processor (e.g.

TDA2579A, see Fig.6), contains the

control and drive functions of the

deflection part in a computer

controlled TV receiver. The TDA8433

replaces all picture geometry settings

which were previously set manually

during manufacture.
