statusis availablein the output registerof theI2C
bus decoder. Generationof burst gate pulses and line fre-
quency signals from the first PLLto drive the
chroma and video circuits. The burst gate pulse also sentto the sandcastle generator. Frame synchro window: [248,352] catching Field frequency selection windows:

against the RGBext. Maximum contraston RGB
(OSD). -10dB rangecontrast controlon RGBext.
Possibility to disable the RGBext insertion
throughthe bus. Oversize blanking capabilityon FB(OSD)(Pin15)
input. The RGB ouputs willbe blanked when the
voltageon Pin15 will exceed the second thresh-
oldat 1.9V (blanking threshold): the whole field blankedbutnot theinserted cut-offpulses. The
OSD insertion thresholdis 0.7V. Automatic cut-off current loop: 2V cut-off range.
Sequential cut-off current measurement during
the three lines after the frame blanking signal.

blanking, memorizationonan internal capacitor. Possibilityto force through the bus the inserted
cut-off pulseson lines 23/24/25(CCIR)in 50Hz
and 60Hz mode. Warmup detector. Beam current limiter DC voltage input.
The beam current limiter control voltage will act contrast first, then the brightness will be de-
creasedwhen contrastattenuationreaches-5dB. Bus controlof the red, green and blue channel

(STV2180 recommended). Automatic standard identification, with possibility force the standard through the bus. ACC doneby peak detectoron synchronous de-
modulationof the burst. Fully integrated killer functions. VCO using two standard crystals: 4.43MHz and
3.58MHz. One crystalis internally selected de-
pendingon the standard selection.3 crystals application capability: one crystal on
Pin XTAL1 (4.43MHzor 3.58MHz), two crystals Pin XTAL2 (3.58MHz only) which can be
selectedby Pin9 out signal.

- OTHER FUNCTIONS:IF CONTROLS
5.1- VolumeControl and MuteThe volume controlvoltage rangeon Pin10is from
0.5Vto 5V.A low voltageon Pin10 (below 0.1V)
will mute the FM demodulatorof theIF circuit
(STV8223). Thus there will beno sound eitheron
the speakeroran audio output plug.
The volume control voltage and the mute level are
controlledby the bus.
5.2- TV/SCART ModeSelectionThe selectionof the TV/External (AV) modeis
controlledby the bus. The selectionis convertedin
two voltageson Pin 11.
The lowest voltage selects the TVmode.
The highest voltage (open collector output with
internal pull-upresistorto VCC)selects theExternal
(AV) mode.
