H-DF OUT
Outputs parabola
waveform for horizontal
dynamic focus.
Mask the pulse in
horizontal blanking if it
is not needed.
In case of not using, it
should be open.
17
LVP IN
LVP detection pin.
Connect reference
voltage used to protect
deflection circuit against
low supply voltage. If
this pin is 5.0 V (typ.) or
below, returns abnormal
detection result to bus
read function.
In case of not using
LVP detection, it should
be open.
DC
18
V-DF OUT
Outputs parabola
waveform for vertical
dynamic focus.
In case of not using, it
should be open.
19
CENTER OUT
Outputs center curve
correction waveform.
Connect this pin to
curve correction input
pin of horizontal sync
IC.
In case of not using, it
should be open.
