BLK in:
Blanking pulse input pin
• Input threshold voltage: 1.4 V
High: V46 ≥ 2.1 V
VCC 5 V (pulse VCC /pin 44)
Low: V46 ≤ 0.9 V
16 µA 40 µA
• Blanking RGB output at input = high
• At input = high, the following Y-signal
corrections are inhibited:
5 V
0 V
Black gradation correction: Detection and
correction inhibited
2.25 V
200 Ω
White gradation correction: Detection and
correction inhibited
