Pin for APC filter
• Color difference signal inputted from
• Clamp pulse uses internal clamp pulse
• Filter pin for killer detection circuit
• Killer turned On (Without color output)
• Output pin of killer detection circuit
• Connect 33 k load resistor of pin 5
• Filter pin for APC detection circuit
• Detection sensitivity becomes large
• When SECAM, APC circuit is stopped
pin 63, 64 is clamped according to
brightness control voltage.
