DESCRIPTION

The STV2118Bis a fully bus controlled IC for TV
luma, chroma and deflectionprocessing.

Used withSTV8224 (PIF/SIF/switches), TDA1771
or TDA8174(framebooster),STV2180(delayline),
it allows to design a PAL/SECAM/NTSC
(BGDKILMN) set with very few external compo­nents and no adjustment.

- Integratedlow passfilter fordeflection part.

- All filtersare tunedwith a referencephaselocked
loop.
The PLL consists of a lowpass filter, a phase
comparator,a loop filter (an external capacitor).
The reference signal is the continuous carrier
wave from the VCO (4.43MHz or 3.58MHz). The
PLLadjusts the center frequency of the lowpass
so that it is equal to the reference signal. The
tuningvoltageof thePLLisusedtoadjustallother
filters.Theclochefilteris finetuned witha second
PLLoperating during frame retrace.

5 - OTHER FUNCTIONS : IF CONTROLS

5.1 - Volume Control and Mute

Thevolumecontrol voltagerangeon Pin 10isfrom

0.5V to 5V. A low voltage on Pin 10 (below 0.2V)

will mute the FM demodulator of the IF circuit
STV8224. It will put the volume at the minimum
level and thus there will be no sound either in TV
mode or SCARTmode.

The volume controlvoltageand the mute level are
controlledby thebus.

5.2- IFStandard and TV/SCART ModeSelection

The selection of IF standard (positive or negative
visionmodulation)and theTV/SCARTmode is con­trolledbythe bus.Theselectionisconvertedinfour
voltageson Pin 21.

The lowest voltage selects the TV mode and the
NEGATIVE vision modulation.

The highest voltage (open collector output with
internal pull-upresistorto V
mode and the NEGATIVE visionmodulation.

The two other intermediate voltages select either
TV mode and POSITIVE vision modulation or
SCARTmode and POSITIVE visionmodulation.

) selects the SCART
