PIN NAME FUNCTION INTERFACE
13 CW OUT An output terminal for the continuous chroma
sub-carrier frequency wave, with an amplitude
of 0.7Vp-p (typ).
Also the dc level shows chroma killer status,
with a level of 3.5V for B/W and 1.5V for
Color.
14 RGB VCC(9V) A Vcc terminal for RGB block, PIF det. Output
and sound output circuit.
-
Supply 9V.
15 YS/YM SW A terminal for switching of EXT RGB Mode
/Spot killer and fast Half tone.
16 EXT.R IN Input terminals for EXT RGB signals. The
17 EXT.G IN signals are clamped by capacitors, therefore
18 EXT.B IN the input impedance should be low, 100 ohms
or less is recommended.
For this input, the brightness and RGB
contrast is adjustable, the ABL/ACL limits the
output level. This ABL/ACL may be turned On
and OFF.
OFF : for small area like OSD
ON : for large area like TELETEXT
(input level 0.7Vp-p/100IRE)
19 Y/C GND The GND terminal for Y/C circuit.
20 R OUT Terminals for R/G/B signal output.
21 G OUT Connect resistances to GND, for the current
22 B OUT source if the slew rate is not enough. Due to
the source current limitation, the resistances
should be 2.0 or more.
