(1) Y delay line built-in : total delay time is approximately 690 ns.
(2) Sharpness control is by using delay line aperture control. (contour emphasis type)
Together with black level extention circuit, high quality picture is achieved.
(3) Chroma trap is built-in : Trap frequency is synchronised with the chroma VCO frequency at 4.43 MHz/3.58
MHz automatically. By I2C bus, the trap can be forced to by-pass. In SECAM mode, about 4.43 MHz free run
frequency is obtained. When in black & white(B/W)mode(killer"On"), the trap is automatically by-passed.
(4) Pedestal clamp filter is built-in.

(2) BPF(4.43 MHz/3.58 MHz), ACC filters are built-in, thus external components are reduced.
(3) By changing the following mode using the I2C bus :
1. PAL/NTSC
2. 4.43 MHz/3.58 MHz
3. Forced PN/Forced SECAM
and together with the SECAM IC for automatic SECAM detection, multi-system application is possible.

(4) Killer output pin is available for system identification by MICOM.
(Killer"On" → 0 V : Either color signal is not properly detected due to wrong system settig, or the color signal
field strength is too weak.
Killer"Off" → 5 V : Color signal is properly detected.)
When killer is on, according to the MICOM control sequence,the mode and VCO frequency will be switched
by means of the I2C bus.
(5) During SECAM, the color difference output pins are put into high impedance.
(6) AN5344(color-compensation IC)and other types of feature IC can be connected because color difference
input pins are available.
(7) It is possible for South American set application.

■ Technical Data (continued)
• Outline of major blocks (continued)
• RGB
(1) OSD is made up of 3 colors of RGB, by using simple analog input, of which input at 0 V is fixed at the
pedestal level.(The input dynamic range is controllable by contrast)
(2) White balance(drive, cutoff)adjustment is implemented by I2C bus.
(3) Spot killer is built-in : When power supply is off, R, G, B, output levels increase, the residue spot that is
visible on the CRT is eliminated.
• Jungle
(1) 2-pin are used for synchronous inputs(Horizontal, Vertical)to improve the synchronisation characteristics of
horizontal and vertical synchronisation.
(2) The horizontal circuit is based on countdown method using a 32 fH ceramic oscillator.
AFC circuit is employing the doubler method.
(3) The vertical circuit is employing the trigger method's countdown circuit, thereby resulting in no adjustment
and stable vertical synchronisation. The pulse output will not be interfered by interlace which is caused by
pattern layout.
(4) Vertical frequency identification circuit is built-in : the output of 50/60 Hz identification is determined
according to the vertical synchronous frequency.(60 Hz → "H")
Below 45 Hz and above 65 Hz, the previous state is hold. After 3 consecutive vertical period, if 60 or 50 Hz
is identifield, the initial output will be changed.

(5) Horizontal lock detection circuit and X-ray protection circuit(Shut down method)are built-in.
(6) Picture centre position is adjustable by I2C bus.(±1.6 µs)
(7) In the case of blue back in a weak field, the vertical trigger can be in off mode(I2C bus).
Thus a stable picture is maintained.
• I2C Bus
(1) There are 15 built-in DAC controls and 13 built-in switches to reduce adjustment for set maker.
(2) Auto-increment function present :
• Sub address 0*: Auto-increment mode
(When the data is sent in consecutive order, the sub-address will be changed in consecutive order, as data is
inputed)
• Sub address 8*: Data refresh mode
(When the data is sent consecutively, it is sent to the same sub-address)

1. For the Control information, for all sub-address, when data goes up, output increases.
(Example : Contrast 00 → contrast min., 7F → contrast max., Brightness 00 → pedestal low, FF → pedestal high)
2. Other control supplementary
(1) 00 : Color
When Color data is 00, chroma output is completely cutoff so that color is off.
(2) 01 : Tint
When tint data is 00, the skin color approaches red.When tint data is 7F, the skin color approaches green.

8-bit DAC 1 section(no switching of sub-section).
(5) 0A : Video Adjust
Data 0*→ composite video min. F*→ composite video max. This control is used to adjust the composite
video level.
(6) 0A : Horizontal Centre
Data *0→ picture moves left. *F→ picture moves right.
(7) 0B : External DAC2 and 04 D7
External DAC2 has 8-bits DAC of 2 sections adjustment.
Data 01 → DC voltage shifts down.
Data FF → DC voltage shifts up.
(8) 0C : External DAC1
Data 00 → DC voltage shifts down.
Data 7F → DC voltage shifts up.
(9) 0D : External DAC3
Data 00 → DC voltage shifts down.
Data 7F → DC voltage shifts up.
