An external capacitor permits to align synchro. pulses, two external resistors determines the detection threshold of synchro pulses. The frame synchronization pulses are locked to a 32s reference signal to perfect interlacing. Horizontal Scanning The horizontal scanning frequency is obtained from a 500kHz VCO. The circuit uses two phase-locked loops (PLL). The first one controls the frequency; the second one, fully integrated, controls the relative phase of the synchronization and the line flyback signals. The first PLL has two times constants : a long time constant during the picture to have a good noise immunity, a short time constant at the beginning of the frame to recapture faster the phase in case of VCR video signal. More over, the PLL is in short time constant three lines before frame pulses occured, it permits to ensure good interlacing when the video signal comes from a VCR tape with high phase error. The horizontal output signal is 28s width. On starting up, horizontal pulses are enabled at VCC = 6.8V. On shutting down, horizontal pulses are inhibited for VCC = 6.2V. Vertical Scanning The windows for the frame sync detection are generated by a count down system. The selection of the windows is determined by the IC status : - video identification off - window : 248/314 - video identification on - window : 248/352 When a sync pulse is detected inside the window a 10.5 lines long pulse is provided to VOUT pin. The count down system provides also the needed signals for the time constant switch, the line PLL inhibition and service signals to the rest of the IC. CHROMA ACC Amplifier, DL Matrix, Permutator and Demodulator The correct chroma subcarrier input, issued from bandpassor bell filter, is internally selected with the standard. The ACC amplifier envolves three stages : the first one select the correct input, the second one the -6dB in picture (PAL mode), the third one is controled by the ACC voltage. The dynamic range is over than 30dB. The chrominance output signal is fed to the delay line. - PAL mode : the adding and substracting direct and delayed signals are performed by the DL matrix function. Two synchronous demodulators multiplies the (B-Y) signal with the 0 degree phase 4.43MHz reference signal and the (R-Y) signal with the alternate 90 deg. 4.43MHz phase reference signal. - SECAM mode : the permutator separatesthe two (B-Y) and (R-Y) subcarriers. These signals are demodulated by two FM demodulators with two external L, C centered on fO(blue) = 4.25MHz and fO(red) = 4.406MHz. 4.43MHz Phase Locked Loop The oscillating frequency of the 4.43MHz crystal oscillator is controlled by the output voltage of the loop filter. The phase detector will lock the 90 degree reference signal to the direct burst signal. A 90 degree phase shifter permits to recover the 0 degree reference signal. A flip-flop driven by line pulses permits to generate the alternate 90 degree signal. ACC Control and Color Killer PAL mode : the direct burst signal is demodulated with the 90 degree reference signal. The demodulation result is used by ACC control and killer function. SECAM mode : ACC control is done by a X2 demodulator. For identification the burst signals of the red and blue lines are demodulated by the external LC connected on Pin 31, it is centered at 4.32MHz. This give positive and negative signals which are inverted by the signal coming out of the SECAM flip-flop. In both standard, if the demodulation result is always positive, the killer capacitor is charged and the standard is identified (color ON). When demodulation result is always negative, the killer capacitor voltage reaches the flip-flop inhibition level, so the alternace sequence is reversed and the capacitor is charged again. In case of no video signal, both killer capacitors voltage are maintained about VCC/2, below the color off threshold. In PAL or SECAM, the ACC control voltage is obtained by the peak detection of the demodulated burst. 3/15 STV2110A Automatic Standard Identification The circuit is alternatelyforced in eachmode during two fields (PAL mode, SECAM mode disabled or SECAM mode, PAL mode disabled). If PALsignal is identified, the alternate PAL/SECAM sequency is locked in PAL mode. To have a SECAM identification, the circuit must memorizes a first SECAM identification, than test the PAL mode and confirm a second SECAM identification. The SECAM identification will take from four to six fields. Output Pin 21, named PS, is high level in PAL mode and low level in SECAM mode. Forced standard : Pin 21 can be used for the purpose : - Pin 21 to HVCC : PAL mode - Pin 21 to ground : SECAM mode VIDEO Input Stage The luminance input is controlled by the contrast control stage which range is 20dB. The luminance and color difference signals are added in the video matrix circuit to obtain the color signals.

Automatic Cut-off Control The black levels of the RGB outputs are controlled with the cut-off loops during three line periods after the frame retrace. The cut-off measurements are sequentially achieved during these three lines. The leakage current measurement is achieved during the frame retrace and memorized on an internal capacitor, thus the circuit is able to extract the cut-off current from the total current measurement. Warm-up Detector At the start-up, the cut-off loops are switch off, a white level is inserted on the luminance signal until a cathode current is detected. Then the cut-off loops are released. RGB Inputs To avoid the black level of the inserted signal differing from the black level of the normal video signal, the external RGB are clamped to the black level of the luminance signal. Therefore, an AC coupling is required for the RGB inputs. The RGB inputs are controlled by a 12dB range contrast control stage.
