Connect a capacitor to hold the
AGC voltage which maintains the
V sawtooth wave at a constant
amplitude.
V pulse output pin. A negative
polarity pulse 3 to 3.5 H width is
output from this pin.
High level: 4.5 V
Low level: 0 V
H drive output pin. This pin is
output at the open collector.
X-ray protection circuit input pin.
When a pulse with a width of 7 V
or more is input, HD output
becomes low and R, G and B
outputs are blanked. This status
is maintained until the power
supply is turned off.
Vilmax = 2.4 V
Vihmin = 3.0 V
H pulse input pin. Inputs a 3 to 5
Vp-p signal via a capacitor.
Jungle system (H/V) GND pin.
