GENERAL
DESCRIPTION
The STV7778S is a monolithic integrated circuit
assembled in a 42 pins shrunk dual in line plastic
package.
The goal of this IC is to control all the functions
related to the horizontal and vertical deflection in a
multimodes or multisync monitor.
As can be seen in the block diagram, the
STV7778S 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.
An internal metal shield give to the STV7778S more
immunity against electromagnetic and electrostatic
fields, and therefore, additional safety for critical
applications (for example, in case of CRTs with
small coated area).
