Technical Information (continued)
Explanation of each block (continued)
3. Video
1) The delay line aperture control (contours emphasis type) is used for sharpness control.
The circuit as well as the black extension circuit realizes a high picture quality.
2) Built-in pedestal clamp filter.
3) Service SW: (Y contrast min., vertical output stop).
4. Chroma
1) The circuit realizes an adjustment free condition by using base band 1HDL (externally attached).
2) Incorporation of ACC filter reduces the number of external components.
3) It is possible to support the other systems by the mode changeover I
2
C bus (1) PAL/NTSC, (2) 4.43 MHz/3.58
MHz, (3) Forced PN/ForcedSECAM.
4) Equipped with the killer output terminal for system discrimination by microcomputer. (When killer is on
0 V, killer is off
5 V)
5) The color difference output terminal becomes a high impedance state at SECAM.
6) Since the circuit is provided with the color difference input terminal, the features of ICs such as the AN5244
(IC for color signal compensation) can be connected.
7) PAL/NTSC, SECAM interface (pin 59)
Note) *: AC component of 4.43 MHz is outputted in the vertical sweep period only.

5. RGB
1) It supports not only the OSD but also the teletext signal in an analog input system.
(The output level is interlocked with the contrast of TV signal side.)
2) The white balance (drive, cut-off) adjustment is performed by I
2
C bus.
6. Jungle
1) The horizontal circuit uses the count down method by 32 f
H
ceramic oscillator. The AFC circuit uses double
method.
2) By the adaption of trigger method count down circuit, the vertical circuit can obtain a stable vertical synchro-
nization without adjustment at all times. The output is pulse signal, so that there is no degradation of interface
due to the influence of pattern layout.
