It is opened from line 258 to line 5.5 (or 264) in 60Hz mode. • the time constants values are chosen by 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 first PLL. The video identification 2 status is available in the output register of the I C 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] 60 Hz mode selec tion 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 : 28µs 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 controlled output voltage to adjust the 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 blanking pulse; the highest threshold (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. 3/25 STV2118B FUNCTIONAL DESCRIPTION (continued) 2 - FILTERS - Integrated trap filter : 1 Q = 1.7 at sharp. min Q= Q = 3.0 at sharp. max fo f−3dB − f−3dB fo Center frequency : - 4.43MHz, 3.58MHz for PAL, NTSC - 4.25MHz, for SECAM (f-3dB = 3 MHz ; -2 0 dB rejection between 4.1MHz and 4.4MHz) - Integrated chroma bandpass : Q = 3.5 Center frequency : 4.43MHz, 3.58MHz - Integrated cloche filter for SECAM : Q = 16 Center frequency : 4.286MHz - 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, a loop filter (an external capacitor). The reference signal is the continuous carrier wave from the VCO (4.43MHz or 3.58MHz). The PLL adjusts the center frequency of the lowpass so that it is equal to the reference signal. The tuning voltage of the PLL is used to adjust all other filters. The cloche filter is fine tuned with a second PLL operating during frame retrace. - - - - - 3 - VIDEO CIRCUIT - 2 RGB inputs : RGB (OSD) input has priority against the RGBext. Maximum contrast on RGB (OSD). -12dB range contrast control on RGBext. 4/25 - 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 and SECAM matrix, specific NTSC matrix when demodulation angles are (0o, 104o). 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.

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 SCART mode. The volume control voltage and the mute level are controlled by the bus. 5.2 - IF Standard and TV/SCART Mode Selection The selection of IF standard (positive or negative vision modulation) and theTV/SCART mode is controlled by the bus. The selection is converted in four voltages on Pin 21. The lowest voltage selects the TV mode and the NEGATIVE vision modulation. The highest voltage (open collector output with internal pull-up resistor to VCC) selects the SCART mode and the NEGATIVE vision modulation. The two other intermediate voltages select either TV mode and POSITIVE vision modulation or SCART mode and POSITIVE vision modulation. 5/25 STV2118B I2C BUS SPECIFICATION General Comments Slave Address : 8A (HEX) (1000101X) WRITE MODE DATA FORMAT Slave Address Register Address Data 1000 1010 (8A) XXS SSSS (from 00 to 11HEX) XXSS SSSS (6 significant bits Max.)
