STV7778S  
DEFLECTION PROCESSOR FOR MULTISYNC MONITOR  
HORIZONTAL  
The goal of this IC is to control all the functions  
related to the horizontal and vertical deflection in a  
multimodes or multisync monitor.  
.
.
.
.
.
DUAL PLL CONCEPT  
SELF-ADAPTIVE (30 TO 70kHz)  
X-RAY PROTECTION INPUT  
DC ADJUSTABLE DUTY-CYCLE  
INTERNAL 1st PLL LOCK/UNLOCK IDENTIFI-  
CATION  
WIDE RANGE DC CONTROLLED H-POSITION  
ON/OFF SWITCH (FOR PWR MANAGEMENT)  
TWO H-DRIVE POLARITIES  
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.  
VERTICAL  
An internal metal shield give tothe STV7778Smore  
immunity against electromagnetic and electrostatic  
fields, and therefore, additional safety for critical  
applications (for example, in case of CRTs with  
small coated area).  
.
VERTICAL RAMP GENERATOR  
45 TO 120Hz AGC LOOP  
DC CONTROLLED V-AMP, V-POS, S-AMP  
AND S-CENTERING  
.

ON/OFF SWITCH  
B+ REGULATOR  
.
INTERNAL PWM GENERATOR FOR B+  
CURRENT MODE STEP-UP CONVERTER  
DC ADJUSTABLE B+ VOLTAGE  
OUTPUT PULSES SYNCHRONISED ON  
HORIZONTAL FREQUENCY  
INTERNAL MAX CURRENT LIMITATION

.
EWPCC  
.
VERTICAL PARABOLA GENERATOR WITH DC  
CONTROLLED KEYSTONE AND AMPLITUDE  
GENERAL  
.
COMPARED WITH THE STV7778, THE  
STV7778S HAS AN INTERNAL METAL SHIELD  
PROTECTION AGAINST OVERVOLTAGE.  
POS/NEG H AND V SYNC POL  
SEPARATED H AND V TTL INPUT  
SHRINK42
