4.2V
Connect a capacitor to generate the V sawtooth
wave.
Power supply for the deflection block.
H drive signal output.
This signal is output with the open collector.
This pin goes high (OFF) during hold-down.
H deflection pulse input for H AFC.
Input an about 5Vp-p pulse via a capacitor. Set
the pulse width to 10 to 12µs. This pin is also
used as the hold-down signal input for the HD
output, and if this pin is 1 [V] or less for a 7V
cycle or longer, the hold-down function operates
and the HD output goes to high (OFF).
In addition, the RGB outputs are all blanked and
the status is returned to the I
Filter for H AFC.
Connect to GND via a capacitor. The H phase
can also be controlled from this pin by leading
current in and out of this capacitor.
As the pin voltage rises, the picture shifts to the
left; as the pin voltage drops, the picture shifts to
the right.
CR connection for the AFC lag-lead filter.
Connect the 32f
GND for the deflection block.
For the CXA2025S, this pin is low (ON) during
hold-down.
H
VCO ceramic oscillator.
