DESCRIPTION
The TDA9103 is a monolithic integrated circuit assembled
in a 42 pins shrunk dual in line plastic package.
This IC controls all the functions related to the horizontal
and vertical deflection in multimodes or multisync monitors.
As can be seen in the block diagram, the TDA9103 includes
the following functions :
- Positive or Negative sync polarities,
- Auto-sync horizontal processing,
- H-PLL lock/unlock identification,
- Auto-sync Vertical processing,
- East/West signal processing block,
- B+ controller,
- Safety blanking output.

T his IC, combined with TDA9205 (RG B preamp),
STV9420/21 or 22 (O.S.D. processor), ST7271 (micro
controller) and TDA8172 (vertical booster), allows to real-
ize very simple and high quality multimodes or multisync
monitors.
