Pin N° 1 2 Name PLL2C H-DUTY 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. Must be connected only to components related to H blocks. Horizontal Section Reference Voltage.
