HORIZONTAL DUAL PLL CONCEPT 150kHz MAXIMUM FREQUENCY SELF-ADAPTATIVE X-RAY PROTECTION INPUT DC ADJUSTABLE DUTY-CYCLE 1st PLL LOCK /UNLOCK INFORMATION WIDE RANGE DC CONTROLLED H-POSITION ON/OFF SWITCH (FOR PWR MANAGEMENT) TWO H-DRIVE POLARITIES
This I C controls all the functions related to the horizontal and vertical deflection in multimodes o r multisync monitors. This IC, combined with TDA9205 (RGB preamp), STV942x (OSD processor), ST727x (micro controller) and T DA817x (vertical booster), allows to realize very simple and high quality multimodes o r multisync monitors.

PIN DESCRIPTION
Pin 1 2 3 4 Name V-FOCUS H -LOCKOUT PLL2C H-DUTY F unction Vertical Dynamic Focus Output First PLL Lock/Unlock Output Second PLL Loop Filter DC Control of Horizontal Drive Output Pulse Duty-cycle. If this Pin is grounded, the Horizontal and Vertical Outputs are inhibited. By connecting a Capacitor on this Pin a Soft-start function may be realized on H -drive Output. Horizontal Flyback Input (positive polarity) Horizontal Section Ground Horizontal Section Reference Voltage, must be filtered VCO Low Threshold Filtering Capacitor VCO High Threshold Filtering Capacitor Horizontal Oscillator Capacitor Horizontal Oscillator Resistor First PLL Loop Filter First PLL Lock/Unlock Time Constant Capacitor. When Frequency is changing, a Blanking Pulse is generated on Pin 23, the duration of this Pulse is proportionnal to the Capacitor on Pin 13. TTL-Compatible Input for PLL1 Output Current Inhibition DC Control for Horizontal Centering X-RAY protection Input (with internal latch function) TTL compatible Horizontal Sync Input Supply Voltage (12V Typ.) Ground Horizontal Drive Output (emiter of internal transistor) Horizontal Drive Output (open collector of internal transistor) Blanking Output, activated during frequency changes, when X-RAY Input is triggered, w hen VS is too low, or when Device is in stand-by m ode (through H-DUTY Pin 2) and during H -FLY, V-FLY, V-SYNC, VSawth retrace. DC Control of Corner Correction Amplitude Vertical Section Signal Ground Memory Capacitor for Automatic Gain Control Loop in Vertical Ramp Generator Vertical Section Reference Voltage Vertical Sawtooth Generator Capacitor DC Control of Vertical S-Shape Amplitude DC Control of Vertical C-Correction Vertical Ramp Output (with frequency independant amplitude and S-Correction) DC Control of Vertical Amplitude Adjustment Vertical Position Reference Voltage Output DC Control of Vertical Position Adjustment TTL-Compatible Vertical Sync Input Geometric Correction Reference Voltage Input Vertical Flyback Input (positive polarity) East /West Pincushion Correction Parabola Output DC Control of Keystone Correction DC Control East/West Pincushion Correction Amplitude Side Pin Balance & Parallelogram Correction Parabola Output DC Control of Parallelogram Correction DC Control of Side Pin Correction Amplitude
