Connect decoupling capacitance for
internal regulator. Connect to GND via a
10µF capacitor.
Sand castle pulse output.
The sand castle pulse is the waveform
obtained by superimposing the burst gate
pulse onto the composite blanking pulse.
H deflection pulse input for H AFC. Input
a 5Vp-p pulse via a capacitor. This pin is
also used as the X-RAY protect signal
Input. If the pin voltage 1V or less for a 7
vertical cycle or longer, then the hold-down
funtion operates. At this time, the HD
output goes to high impedance, the RGB
output are blanked and "1" is output to the
status register HNG. To release this status,
turn the power off and then on again.
Output the differential waveform of
luminance signal for the VM (Velosity
Modulation) system. This pin is also used
as the V protect signal input.
When a large current (4mA) is pulled from
this pin, the RGB outputs are all blanked
and "1" is output to the status register
VNG.
