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 proportionnel 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, when
VS is too low, or when Device is in stand-by mode (through H-DUTY Pin 2) and during H-FLY,
V-FLY, V-SYNC, VSawth retrace.
Moire Output
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
