Blanking Power Supply Pin, 10.8V ~ 13.2V
The VP pin must connect to power supply through 10ohm resistor with 0.1μF
ceramic capacitor in parallel with a 1μF electrolytic capacitor to VSS1.
Slow Blanking Output Pin for TV
A 470ohm ±5% resistor must be connected between the TVSB pin and SCART
connector.
Audio Ground Pin , 0V

Rch Positive Analog Input Pin
Lch Negative Analog Input Pin
Lch Positive Analog Input Pin
Negative Voltage Output Pin
Connect to VSS2 with a 1.0μF capacitor that should have the low ESR (Equivalent
Series Resistance)
over all temperature range. When this capacitor has the polarity,
the positive polarity pin should be connected to the VSS2 pin. Non polarity
capacitors can also be used.
Negative Charge Pump Capacitor Terminal Pin
Connect to CP with a 1.0μF capacitor that should have the low ESR (Equivalent
Series Resistance) over all temperature range. When this capacitor has the polarity,
the positive polarity pin should be connected to the CP pin. Non polarity capacitors
can also be used.
Positive Charge Pump Capacitor Terminal Pin
Connect to CN with a 1.0μF capacitor that should have the low ESR (Equivalent
Series Resistance) over all temperature range. When this capacitor has the polarity,
the positive polarity pin should be connected to the CP pin. Non polarity capacitors
can also be used.
Charge Pump Ground Pin , 0V
Charge Pump Power Supply Pin: 3.13V ~ 3.47V
