Philips SemiconductorsProduct specificationPAL/NTSC decoderTDA3566AFUNCTIONAL DESCRIPTIONThe TDA3566A is a furtherdevelopment of the TDA3562A. It hasthe same pinning and nearly thesame application. The differencesbetween the TDA3562A and theTDA3566A are as follows:• The NTSC-application has largelybeen simplified. In the event ofNTSC the chrominance signal isnow internally coupled to thedemodulators, automaticchrominance control (ACC) andphase detectors. The chrominanceoutput signal (pin 28) is thussuppressed. It follows that theexternal switches and filters whichare required for the TDA3562A arenot required for the TDA3566A.There is no difference between theamplitudes of the colour outputsignals in the PAL or NTSC mode.• The clamp capacitor at pins 10, 20and 21 in the black-levelstabilization loop can be reduced to100 nF provided the stability of theloop is maintained. Loop stabilitydepends on complete application.The clamp capacitors receive apre-bias voltage to avoid colouredbackground during switch-on.• The crystal oscillator circuit hasbeen changed to prevent parasiticoscillations on the third overtone ofthe crystal. Consequently theoptimum tuning capacitance mustbe reduced to 10 pF.• The hue control has been improved(linear).Luminance amplifierThe luminance amplifier is voltagedriven and requires an input signal of450 mV peak-to-peak (positivevideo). The luminance delay line mustbe connected between the IFamplifier and the decoder.The input signal is AC coupled to theinput (pin 8). After amplification, theblack level at the output of thepreamplifier is clamped to a fixed DClevel by the black level clampingcircuit. During three line periods aftervertical blanking, the luminancesignal is blanked out and the blacklevel reference voltage is inserted bya switching circuit.This black level reference voltage iscontrolled via pin11 (brightness). Atthe same time the RGB signals areclamped. Noise and residual signalshave no influence during clampingthus simple internal clamping circuitryis used.Chrominance amplifiersThe chrominance amplifier has anasymmetrical input. The input signalmust be AC coupled (pin 4) and havea minimum amplitude of40 mV peak-to-peak.The gain control stage has a controlrange in excess of 30 dB, themaximum input signal must notexceed 1.1 V peak-to-peak,otherwise clipping of the input signalwill occur.From the gain control stage thechrominance signal is fed to thesaturation control stage. Saturation islinearly controlled via pin 5. Thecontrol voltage range is 2 to 4 V, theinput impedance is high and thesaturation control range is in excessof 50 dB.The burst signal is not affected bysaturation control. The signal is thenfed to a gated amplifier which has a12 dB higher gain during thechrominance signal. As a result thesignal at the output (pin 28) has aburst-to-chrominance ratio which is6 dB lower than that of the inputsignal when the saturation control isset at −6 dB.The chrominance output signal is fedto the delay line and, after matrixing,is applied to the demodulator inputpins (pins 22 and 23). These signalsare fed to the burst phase detector. Inthe event of NTSC the chrominancesignal is internally coupled to thedemodulators, ACC and phasedetectors.Oscillator and identification circuitThe burst phase detector is gatedwith the narrow part of the sandcastlepulse (pin 7). In the detector the(R−Y) and (B−Y) signals are added toprovide the composite burst signalagain.This composite signal is comparedwith the oscillator signaldivided-by-2 (R−Y) reference signal.The control voltage is available atpins 24 and 25, and is also applied tothe 8.8 MHz oscillator. The 4.4 MHzsignal is obtained via the divide-by-2circuit, which generates both the(B−Y) and (R−Y) reference signalsand provides a 90° phase shiftbetween them.The flip-flop is driven by pulsesobtained from the sandcastledetector. For the identification of thephase at PAL mode, the (R−Y)reference signal coming from the PALswitch, is compared to the verticalsignal (R−Y) of the PAL delay line.This is carried out in the H/2 detector,which is gated during burst.When the phase is incorrect, theflip-flop gets a reset from theidentification circuit. When the phaseis correct, the output voltage of theH/2 detector is directly related to theburst amplitude so that this voltagecan be used for the ACC.To avoid 'blooming-up' of the pictureunder weak input signal conditionsthe ACC voltage is generated by peakdetection of the H/2 detector outputsignal. The killer and identificationcircuits receive their information froma gated output signal of H/2 detector.Killing is obtained via the saturationcontrol stage and the demodulators toobtain good suppression.February 1994 5

Philips SemiconductorsProduct specificationPAL/NTSC decoderTDA3566AThe time constant of the saturationcontrol (pin 5) provides a delayedswitch-on after killing. Adjustment ofthe oscillator is achieved by variationof the burst phase detector loadresistance between pins 24 and 25(see Fig.8).With this application the trimmercapacitor in series with the 8.8 MHzcrystal (pin 26) can be replaced by afixed value capacitor to compensatefor unbalance of the phase detector.DemodulatorThe (R−Y) and (B−Y) demodulatorsare driven by the colour differencesignals from the delay-line matrixcircuit and the reference signals fromthe 8.8 MHz divider circuit. The (R−Y)reference signal is fed via thePAL-switch. The output signals arefed to the R and B matrix circuits andto the (G−Y) matrix to provide the(G−Y) signal which is applied to theG-matrix. The demodulation circuitsare killed and blanked by by-passingthe input signals.NTSC modeThe NTSC mode is switched on whenthe voltage at the burst phasedetector outputs (pins 24 and 25) isadjusted below 9 V.To ensure reliable application thephase detector load resistors areexternal. When the TDA3566A isused only for PAL these two 33 kΩresistors must be connected to +12 V(see Fig.8).For PAL/NTSC application the valueof each resistor must be reduced to20 kΩ (with a tolerance of 1%) andconnected to the slider of apotentiometer (see Fig.9). Theswitching transistor brings the voltageat pins 24 and 25 below 9 V whichswitches the circuit tot the NTSCmode.The position of the PAL flip-flopensures that the correct phase of the(R−Y) reference signal is supplied tothe (R−Y) demodulator.The drive to the H/2 detector is nowprovided by the (B−Y) referencesignal. In the PAL mode it is driven bythe (R−Y) reference signal. Huecontrol is realized by changing thephase of the reference drive to theburst phase detector.This is achieved by varying thevoltage at pins 24 and 25 between7.0 V and 8.5 V, nominal position7.65 V. The hue control characteristicis shown in Fig.6.RGB matrix and amplifiersThe three matrix and amplifier circuitsare identical and only one circuit willbe described.The luminance and the colourdifference signals are added in thematrix circuit to obtain the coloursignal, which is then fed to thecontrast control stage.The contrast control voltage issupplied to pin 6 (high-inputimpedance). The control range is+5 dB to −11.5 dB nominal. Therelationship between the controlvoltage and the gain is linear (seeFig.3).During the 3-line period after blankinga pulse is inserted at the output of thecontrast control stage. The amplitudeof this pulse is varied by a controlvoltage at pin 11. This applies avariable offset to the normal blacklevel, thus providing brightnesscontrol.The brightness control range is 1 V to3.6 V. While this offset level ispresent, the black-current inputimpedance (pin 18) is high and theinternal clamp circuit is activated. Theclamp circuit then compares thereference voltage at pin 19 with thevoltage developed across theexternal resistor network R A andR B (pin 18) which is provided bypicture tube beam current.The output of the comparator isstored in capacitors connected frompins 10, 20 and 21 to ground whichcontrols the black level at the output.The reference voltage is composedby the resistor divider network and theleakage current of the picture tubeinto this bleeder. During verticalblanking, this voltage is stored in thecapacitor connected to pin 19, whichensures that the leakage current ofthe CRT does not influence the blackcurrent measurement.The RGB output signals can neverexceed a level of 10.6 V. When thesignal tends to exceed this level theoutput signal is clipped. The blacklevel at the outputs (pins 13, 15 and17) will be approximately 3 V. Thislevel depends on the spread of theguns of the picture tube. If a beamcurrent stabilizer is not used it ispossible to stabilize the black levels atthe outputs, which in this applicationmust be connected to the blackcurrent measuring input (pin 18) via aresistor network.February 1994 6

Philips SemiconductorsProduct specificationPAL/NTSC decoderTDA3566AData insertionEach colour amplifier has a separateinput for data insertion.A 1 V peak-to-peak input signalprovides a 3.8 V peak-to-peak outputsignal.To avoid the black-level of theinserted signal differing from the blacklevel of the normal video signal, thedata is clamped to the black level ofthe luminance signal. Therefore ACcoupling is required for the datainputs.To avoid a disturbance of the blankinglevel due to the clamping circuit, thesource impedance of the driver circuitmust not exceed 150 Ω. The datainsertion circuit is activated by thedata blanking input (pin 9). When thevoltage at this pin exceeds a level of0.9 V, the RGB matrix circuits areswitched off and the data amplifiersare switched on.To avoid coloured edges, the datablanking switching time is short. Theamplitude of the data output signals iscontrolled by the contrast control atpin 6. The black level is equal to thevideo black level and can be variedbetween 2 and 4 V (nominalcondition) by the brightness controlvoltage at pin 11.Non-synchronized data signals do notdisturb the black level of the internalsignals.Blanking of RGB and data signalsBoth the RGB and data signals canbe blanked via the sandcastle input(pin 7). A slicing level of 1.5 V is usedfor this blanking function, so that thewide part of the sandcastle pulse isseparated from the remainder of thepulse. During blanking a level of +1 Vis available at the output. To preventparasitic oscillations on the thirdovertone of the crystal the optimumtuning capacitance should be 10 pF.LIMITING VALUESIn accordance with the Absolute Maximum Rating System (IEC 134).SYMBOL PARAMETER MIN.

Philips SemiconductorsProduct specificationPAL/NTSC decoderTDA3566A8. These signal amplitudes are determined by the ACC circuit of the reference part.9. This value depends on the gain setting of the RGB output amplifiers and the drift of the picture tube guns. Higherblack level values are possible (up to 5 V) however, in that condition the amplitude of the available output signal isreduced.10. The variation of the black-level during brightness control in the three different channels is directly dependent on thegain of each channel. Discolouration during adjustments of contrast and brightness does not occur becauseamplitude and the black-level change with brightness control are directly related.11. With respect to the measuring pulse.12. This difference occurs when the source impedance of the data signals is 150 Ω and the black level clamp pulse widthis 4 µs (sandcastle pulse). For a lower impedance the difference will be lower.13. For correct operating of the black level stabilization loop, the leading and trailing edges of the sandcastle pulse(measured between 1.5 V and 3.5 V) must be within 200 ns and 600 ns respectively.14. The voltage at pins 24 and 25 can be changed by connecting the load resistors (20 kΩ, 1%, in this condition) to theslider bar of the hue control potentiometer (see Fig.6). When the transistor is switched on, the voltage at pins 24 and25 is reduced below 9 V, and the circuit is switched to NTSC mode. The width of the burst gate is assumed to be4 µs typical.February 1994 13
