FUNCTION
INTERFACE
23
IK IN
An input terminal to sense AKB cathode
current.
Connect this terminals to GND if the AKB
system is not being used.
24
V RAMP
A terminal should be connected wiht a
capacitor to generate the V.Ramp signal.
The V.Ramp amplitude is kept constant by
the V.AGC.
25
V NFB
An input terminal for the V saw-tooth signal
feedback.
If the DC voltage on this pin is less than 1.7V,
it blanks RGB output for V guard.
26
V OUT
An output terminal for the vertical driving
pulses.
