FUNCTIONAL DESCRIPTION (continued)
4 - CHROMA CIRCUIT
4.1 - PAL/NTSC Decoders
- SVHS inputs ; bus controlled SVHS mode.
- 30dB range ACC
- Use of an external base band delay line
(STV2180 recommended)
- Automatic standard identification, with possibility
to force the standard through the bus.
- ACC done by peak detector on synchronous de-
modulation of the burst
- ACC overload.
- Fully integrated killer functions.
- VCO using two standard crystals : 4.43MHz and
3.58MHz. One crystal is internally selected de-
pending on the standard selection.
- 3 crystals application capability : one crystal on
Pin XTAL1 (4.43MHz or 3.58MHz), two crystals
on Pin XTAL 2 (3.58MHz only) which can be
selected by Pin 9 out signal.
XTAL SPECIFICATION :
Frequency
4.43361 9MHz (PAL)
3.579545MHz(NTSC M)
3.575611MHz(PAL M)
3.582056MHz(PAL N)
Motional Capacity
13fF ± 3fF
11fF ± 3fF
9fF ± 1fF
10fF ± 2fF
Vibration mode : Fondamental,series resonance
(no serial capacitor)
Resonance resistance : < 70Ω
Shunt capacitance : < 7pF
Spurious response : No resonance at 3*fo ±3kHz
- 0o and ±90o demodulation angles for PAL
- (0o, 90o) or (0o,104o) = demodulation angles for
NTSC. The selection of 90o or 104o is made
through the bus.
- Bus control Hue adjustment in NTSC mode.
- NTSC Automatic Flesh control. Bus controlled
disable. Two automatic flesh control charac-
teristics : the first one with ±20o correction and a
total action range of ±90o, the second one with
±12o maximumcorrection and a totalactionrange
of ±60o. The selection of the flesh characteristic
is bus controlled.
- Switchable Chroma demodulator gain (+6dB) for
NTSC only application, when no external chroma
delay line is used.
4.2 - Standard Identification
- 3 identification sequences : XTAL1 (crystal on
Pin 3), XTAL2-1 (first crystal on Pin 2), XTAL2-2
(second crystal on Pin 2). Parallel identificationof
PAL and NTSC.
- Blanking of the (R-Y) and B-Y) outputs during
color search mode.
5 - OTHER FUNCTIONS : IF CONTROLS
5.1 - Volume Control and Mute
The volume control voltage range on Pin 10 is from
0.5V to 5V. A low voltage on Pin 10 (below 0.1V)
will put the volume to minimum and mute the FM
demodulatorof the IF circuit (STV8223).Thus there
will be no sound either on the speaker or an audio
output plug.
The volume control voltage and the mute level are
controlled by the bus.
5.2 - TV/External Mode Selection
The selection of theTV/External (AV) mode is con-
trolled by the bus. The selection is converted in two
voltages on Pin 11.
The lowest voltage selects the TV mode.
The highest voltage (open collector output with
internal pull-up resistor to VCC) selects the Exter-
nal (AV) mode.
