TERMINAL FUNCTIONS
MAXIMUM RATINGS
You can select the Double Scan Mode (External CP (Clamping Pulse) input Mode), by connecting Pin 23 to DEF
V
When Double Scan Mode, function of Pin 24 and 25 are changed.
The function of Pin 24 is curve correction input, that of Pin 25 is FBP (Flay Back Pulse) input.
The input signals of Y2, U / I and V / I inputs (Pin 53, 52 and 51), Analog OSD inputs (Pin 39, 38 and 37),
Analog RGB inputs (Pin 35, 34 and 33) are clamped of the internal CP based on the Y1 / Sync input (Pin 15).
The function of Pin 24 is EXT / BPP (Note) input, that of Pin 25 is H / V BLK (blanking) input.
The input signals of Y2, U / I and V / I inputs (Pin 53, 52 and 51), Analog OSD inputs (Pin 39, 38 and 37),
Analog RGB inputs (Pin 35, 34 and 33) are clamped of the external CP based on Pin 24.
In case of Double Scan Mode, bus “V-BLK” should be set (1) ; OFF.
