Description
4
Ys in:
VCC 5 V (pulse VCC /pin 44)
OSD switch signal input pin
• Input threshold voltage: 1.4 V
1) 2.1 V < V4
40 µA
Outputs the OSD signal inputted from pins
13, 14 and 15.
2) V4 < 0.9 V
Outputs the OSD signal either from pins
9, 10, 11 or Pins 37, 38, 39.
• Priority of signal switching

• Force the RGB output down to BLK level
when the input = high. At this time, BLKSW
(I2C) and the single color adjustment SW
(I2C) become invalid and the IK clamp pulse
is not outputted.
