Description

Output of luminance signal differential

waveform for VM (Velocity Modulation).

The phase of VM output is synchronized

to the phase of RGB output.

It is approximately 250ns ahead of RGB

output.

This pin is also used for V protect signal

input. When the large current (4mA) is

forcibly drawn through this pin, all RGB

output is blanked, and 1 is output to the

status register VNG.

Decoupling capacitance for the regulator

within the IC.

The 47µF capacitor is connected to GND.

Sand castle pulse output.

The sand castle pulse is a waveform

superimposed with the burst gate pulse on

the composite blanking pulse.

H deflection pulse input for H AFC.

The 5Vp-p pulse is input via a capacitor.

Since this pin is also used to input an X-

RAY protect signal, a hold down function

activates if this pin's voltage goes above a

"7V cycle" and below 1V. If this occurs,

HD output goes high impedance, RGB

output is blanked, and 1 is output to the

50µA

100µA status register HNG. It is necessary to

turn the IC's power OFF then ON again to

cancel this status.
