FUNCTIONAL DESCRIPTION 1 - DEFLECTION CIRCUIT
Note : [X,Y] : line number referred to the internal line counter numbering
- Fully integrated synch. separator, with a low pass filter, a black level alignment of the Y/CVBS input, a slicing level at 2/3,1/3of the sync. pulse amplitude. - Frame sync. pulse locked on 2 fH frequency to perfect interlace. - 500kHz VCO with an externalceramic resonator. - Two phase locked loops * the first PLL locks the VCO on the video signal frequency, * the second PLL compensates the line transistor storage time. - Three time constants for the first PLL. * thelong timeconstantis usedfor normaloperation * the short time constant is automatically used during the frame retrace and in search mode of VCR when the frame pulse is outside [258,264] and [309,314]. * very long time constant when no video recognition Time constants in normal operation (automatic selection of time constants) : 50Hz input signal : - short time constant : [306, 21] - long time constant : the rest of the field 60Hz input signal : - short time constant : [0, 16] - long time constant : the rest of the field * inhibition of the first PLL : the first locked loop is opened from line 309 to line 4.5 (or 314) in 50Hz mode. It isopened from line 258 to line 5.5 (or 264) in 60Hz mode. * the time constantsvalues are chosenby means of external components. * possibility to force the short time constant through the bus. * possibility to force the very long time constant through the bus. - Video identification : coincidence detector between the line synchro top and a line frequency window from the firstPLL. The video identification status is available in the output register of the I 2C bus decoder. - Generation of burst gate pulses and line frequency signals from the first PLL to drive the chroma and video circuits. The burst gate pulse is also sent to the sandcastle generator. - Frame synchro window : [248, 352] catching - Field frequency selection windows : [248, 288] 6 0 Hz mo de s e le c t io n if two consecutive frame pulses occur inside this window,otherwise 50Hz mode selection. [288, 352] 50Hz mode selection window
- frame blanking pulse : from line 0 to 21 in 50Hz mode from line 0 to 16 in 60Hz mode - Vertical output pulse is 10.5 lines long. - Horizontal output pulse : 28s line pulse on an open collector output; - Start up circuit : the horizontal output is at a high level when VCC increases from 0 to 6.8V. On shutting down, horizontal pulses are disabled when VCC is below 6.2V. - Soft-start circuit : the duty cycle of the horizontal output is 78 % (Thigh/(Thigh + TLow))when VCC1 is lower than (0.75 x VCC2), during the rising time. During the falling time, a 78% duty cycle HOUT pulse is provided when VCC1 is lower than (0.60 x VCC2). - Possibility to disable the horizontal output pulse through the bus (force a high level on HOUT). - Horizontal position adjustment controlled by bus. - Bus controlledoutput voltage to adjustthe vertical amplitude; this voltage permits to adjust the slope of the vertical sawtooth generated by the external frame booster. - Bus controlled vertical position ; the high level of the vertical pulse permits to adjust the vertical position. - Bus controlled 4/3-16/9 selection : the low level of the vertical pulse is 0.1V when 16/9 is selected, 2V when 4/3 is selected. - Combined flyback input and sandcastle output (Pin 37). Two thresholds on LFB/SCO Pin : The lowest threshold (0.7V) permits to extract the line blankingpulse; the highestthreshold(2V) permits to extract the line pulse for PLL2. The sandcastle signal at Pin 37 is used to control the external baseband chroma delay line. 2 - FILTERS - Integrated trap filter :
Q= 1 fo f-3dB - f-3dB fo
Q = 1.7 at sharp. min Q = 3.0 at sharp. max
-
Center frequency : - 4.43MHz, 3.58MHz for PAL, NTSC Integrated chroma bandpass : Q = 3.5 Center frequency : 4.43MHz, 3.58MHz Integrated delay line : Bandwidth = 8MHz Integrated low pass filter for deflection part. All filters are tuned with a reference phase locked loop. The PLL consists of a lowpass filter, a phase comparator,aloopfilter(anexternalcapacitor).The referencesignalis the continuouscarrierwavefrom the VCO (4.43MHz or 3.58MHz). The PLL adjusts the center frequency of the lowpass so that it is equal to the referencesignal.The tuning voltage of the PLL is used to adjust all other filters.

FUNCTIONAL DESCRIPTION (continued) 3 - VIDEO CIRCUIT - 2 RGB inputs : RGB (OSD) input has priority against the RGBext. Maximum contrast on RGB (OSD). -10dB range contrast control on RGBext. Possibility to disable the RGBext insertion through the bus. - Oversize blanking capability on FB(OSD)(Pin15) input. The RGB ouputs will be blanked when the voltage on Pin 15 will exceed the second threshold at 1.9V (blanking threshold) : the whole field is blanked but not the inserted cut-off pulses. The OSD insertion threshold is 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. Leakage current measurement during the frame blanking, memorization on an internal capacitor. - Possibility to force through the bus the inserted cut-off pulses on lines 23/24/25(CCIR) in 50Hz and 60Hz mode. - Warm up detector. - Beam current limiter DC voltage input. The beam current limiter control voltage will act on contrast first, then the brightness will be decreased when contrast attenuationreaches -5dB. - Bus control of the red, green and blue channel gain (White point adjustment) - Bus control of the red and green DC levels (black point adjustment) - PAL matrix, specific NTSC matrix when demoduo o lation angles are (0 , 104 ). - Switch-off of the trap filter in SVHS mode. - Bus controlled contrast on luminance (20dB range) - Bus controlled saturation (50dB range) - Bus controlled brightness : 40% range at maximum contrast. - Bus controlled sharpness (peaking). - Noise coring function on sharpness. - Bus controlled blue screen feature 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 demodulation of the burst. - Fully integrated killer functions. - VCO using two standard crystals : 4.43MHz and 3.58MHz. One crystal is internally selected de4/24
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 : 4.433619MHz (PAL) 3.579545MHz (NTSC M) 3.575611MHz(PAL M) 3.582056MHz (PAL N) Vibration mode : Fondamental,series resonance (no serial capacitor) Motional capacity : 13fF 3fF Resonance resistance : < 70 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. - NTSCautomaticfleshcontrol.Buscontrolleddisable. - Switchable chroma demodulator gain (+6dB) for NTSC only application, when no external chroma delay line is used. 4.2 - Standard Identification - Sequential identification. - 3 identification sequences : XTAL1 (4.43MHz) mode to identify either PAL or NTSC, XTAL2 (3.58MHz)modeto identifyeitherPALor NTSC, no SECAMsignalchecking. In case of singlestandard operation,we recommendto force this standardby the bus which permits the use of only one crystal. - 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 mute the FM demodulator of 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/SCART Mode Selection The selection of the TV/External (AV) mode is controlled 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 External (AV) mode.

Notes :
