Pin 41 H-out (mode SW)
You can select the Double Scan Mode (external CP (clamping pulse) input mode), by connecting Pin 41 to
DEF VCC. (the threshold of pin 23: 8.7 V = DEF VCC 0.3 V)
When Double Scan Mode, function of Pin 38 and 40 are changed.
Normal Scan (internal CP) Mode: Pin 41 H-out
The function of Pin 40 is curve correction input, that of Pin 38 is FBP (flay back pulse) input.
The input signals of Y2, U/I and V/I inputs (pin 1, 2 and 3), Analog OSD inputs (pin 18, 19 and 20),
Analog RGB inputs (pin 22, 24 and 25) are clamped of the internal CP based on the Y1/Sync input (pin
52).
Double Scan (external CP input) Mode: Pin 41 H-out
The function of Pin 40 is EXT/BPP (Note 2) input, that of Pin 38 is H/V BLK (blanking) input.
The input signals of Y2, U/I and V/I inputs (pin 1, 78 and 80), Analog OSD inputs (pin 18, 19 and 20),
Analog RGB inputs (pin 22, 24 and 25) are clamped of the external CP based on Pin 40.
In case of Double Scan Mode, bus “V-BLK” should be set (1); OFF.
