FUNCTIONAL DESCRIPTION Vision IF amplifier The vision IF amplifier consists of three AC-coupled differential amplifier stages. Each differential stage comprises a feedback network controlled by emitter degeneration. Tuner and VIF AGC The AGC capacitor voltage is transferred to an internal IF control signal, and is fed to the tuner AGC to generate the tuner AGC output current (open-collector output). The tuner AGC take-over point can be adjusted. This allows the tuner and the SWIF filter to be matched to achieve the optimum IF input level. The AGC detector charges/discharges the AGC capacitor to the required voltage for setting of VIF and tuner gain in order to keep the video signal at a constant level. Therefore for negative video modulation the sync level and for positive video modulation the peak white level of the video signal is detected. In order to reduce the reaction time for positive modulation, where a very large time constant is needed, an additional level detector increases the discharging current of the AGC capacitor (fast mode) in the event of a decreasing VIF amplitude step. The additional level information is given by the black-level detector voltage. Frequency-Phase detector (FPLL) The VIF-amplifier output signal is fed into a frequency detector and into a phase detector via a limiting amplifier. During acquisition the frequency detector produces a DC current proportional to the frequency difference between the input and the VCO signal. After frequency lock-in the phase detector produces a DC current proportional to the phase difference between the VCO and the input signal. The DC current of either frequency detector or phase detector is converted into a DC voltage via the loop filter, which controls the VCO frequency. In the event of positive modulated signals the phase detector is gated by composite sync in order to avoid signal distortion for overmodulated VIF signals. VCO, travelling wave divider and AFC
TDA9812
The VCO operates with a resonance circuit (with L and C in parallel) at double the PC frequency. The VCO is controlled by two integrated variable capacitors. The control voltage required to tune the VCO from its freerunning frequency to actually double the PC frequency is generated by the Frequency-Phase detector and fed via the loop filter to the first variable capacitor (FPLL). This control voltage is amplified and additionally converted into a current which represents the AFC output signal. The VCO centre frequency can be decreased (required for L/L accent standard) by activating an additional internal capacitor. This is achieved by using the L/L accent switch. In this event the second variable capacitor can be controlled by a variable resistor at the L/L accent switch for setting the VCO centre frequency to the required L/L accent value. At centre frequency the AFC output current is equal to zero. The oscillator signal is divided-by-two with a Travelling Wave Divider (TWD) which generates two differential output signals with a 90 degree phase difference independent of the frequency. Video demodulator and amplifier The video demodulator is realized by a multiplier which is designed for low distortion and large bandwidth. The vision IF input signal is multiplied with the `in phase' signal of the travelling wave divider output. In the demodulator stage the video signal polarity can be switched in accordance with the TV standard. The demodulator output signal is fed via an integrated low-pass filter for attenuation of the carrier harmonics to the video amplifier. The video amplifier is realized by an operational amplifier with internal feedback and high bandwidth. A low-pass filter is integrated to achieve an attenuation of the carrier harmonics for B/G and L standard. The standard dependent level shift in this stage delivers the same sync level for positive and negative modulation. The video output signal is 1 V (p-p) for nominal vision IF modulation.

Video buffer For an easy adaption of the sound traps an operational amplifier with internal feedback is used in the event of B/G and L standard. This amplifier is featured with a high bandwidth and 7 dB gain. The input impedance is adapted for operating in combination with ceramic sound traps. The output stage delivers a nominal 2 V (p-p) positive video signal. Noise clipping is provided. SIF amplifier and AGC for AM sound The sound IF amplifier consists of two AC-coupled differential amplifier stages. Each differential stage comprises a controlled feedback network provided by emitter degeneration. The SIF AGC detector is related to the SIF input signals (average level of AM carrier) and controls the SIF amplifier to provide a constant SIF signal to the AM demodulator. The SIF AGC reaction time is set to `slow' for nominal video conditions. But with a decreasing VIF amplitude step the SIF AGC is set to `fast' mode controlled by the VIF AGC detector. Intercarrier mixer The intercarrier mixer is realized by a multiplier. The VIF amplifier output signal is fed to the intercarrier mixer and converted to intercarrier frequency by the regenerated picture carrier (VCO). The mixer output signal is fed via a high-pass for attenuation of the video signal components. AM demodulator The AM demodulator is realized by a multiplier. The modulated SIF amplifier output signal is multiplied in phase with the limited (AM is removed) SIF amplifier output signal. The demodulator output signal is fed via an integrated low-pass filter for attenuation of the carrier harmonics to the AF amplifier. FM detector The FM detector consists of a limiter, an FM-PLL and an AF amplifier. The limiter provides the amplification and limitation of the FM sound intercarrier signal before demodulation. The result is high sensitivity and AM suppression. The amplifier consists of 7 stages which are internally AC-coupled in order to minimize the DC offset and to save pins for DC decoupling.
TDA9812
The FM-PLL consists of an integrated relaxation oscillator, an integrated loop filter and a phase detector. The oscillator is locked to the FM intercarrier signal, output from the limiter. As a result of locking, the oscillator frequency tracks with the modulation of the input signal and the oscillator control voltage is superimposed by the AF voltage. The FM-PLL operates as an FM-demodulator The AF amplifier consists of two parts: * The AF preamplifier for FM sound is an operational amplifier with internal feedback, high gain and high common mode rejection. The AF voltage from the PLL demodulator, by principle a small output signal, is amplified by approximately 33 dB. The low-pass characteristic of the amplifier reduces the harmonics of the intercarrier signal at the sound output terminal, at which the de-emphasis network for FM sound is applied. An additional DC control circuit is implemented to keep the DC level constant, independent of process spread. * The AF output amplifier (10 dB) provides the required output level by a rail-to-rail output stage. This amplifier makes use of an input selector for switching to AM, FM de-emphasis or mute state, controlled by the standard switching voltage and the mute switching voltage. Internal voltage stabilizer and 12VP-reference The bandgap circuit internally generates a voltage of approximately 1.25 V, independent of supply voltage and temperature. A voltage regulator circuit, connected to this voltage, produces a constant voltage of 3.6 V which is used as an internal reference voltage. For all audio output signals the constant reference voltage cannot be used because large output signals are required. Therefore these signals refer to half the supply voltage to achieve a symmetrical headroom, especially for the rail-to-rail output stage. For ripple and noise attenuation the 12VP voltage has to be filtered via a low-pass filter by using an external capacitor together with an integrated resistor (fg = 5 Hz). For a fast setting to 12VP an internal start-up circuit is added.

Values of video and sound parameters are decreased at VP = 4.5 V. 2. This parameter is not tested during production and is only given as application information for designing the television receiver. 3. Loop bandwidth BL = 60 kHz (natural frequency fn = 15 kHz; damping factor d = 2; calculated with sync level within gain control range). Resonance circuit of VCO: Q0 > 50; Cext = 8.2 pF 0.25 pF; Cint 8.5 pF (loop voltage approximately 2.7 V). 4. Temperature coefficient of external LC-circuit is equal to zero. 5. Vi IF = 10 mV RMS; f = 1 MHz (VCO frequency offset related to picture carrier frequency); white picture video modulation. 6. Vi IF signal for nominal video signal. 7. Offset current measured between pin 7 and half of supply voltage (VP = 2.5 V) under the following conditions: no input signal at VIF input (pins 1 and 2) and VIF amplifier gain at minimum (V28 = VP). Due to sample-and-hold mode of the FPLL in L standard, the leakage current of the loop filter capacitor (C = 220 nF) should not exceed 500 nA. 8. Measurements taken with SAW filter G1962 (sound shelf: 20 dB); loop bandwidth BL = 60 kHz. a) Modulation VSB; sound carrier OFF; fvideo > 0.5 MHz. b) Sound carrier ON; SIF SAW filter L9453; fvideo = 10 kHz to 10 MHz. 9. The 7 dB buffer gain accounts for 1 dB loss in the sound trap. Buffer output signal is typical 2 V (p-p), in event of CVBS video amplifier output typical 1 V (p-p). If no sound trap is applied a 330 resistor must be connected from output to input (from pin 21 to pin 22). 10. The leakage current of the AGC capacitor should not exceed 1 A at B/G standard respectively 10 nA current at L standard. Larger currents will increase the tilt. 11. S/N is the ratio of black-to-white amplitude to the black level noise voltage (RMS value, pin 10). B = 5 MHz weighted in accordance with "CCIR 567".

12. The intermodulation figures are defined: 1.1 = 20 log (V0 at 4.4 MHz/V0 at 1.1 MHz) + 3.6 dB; 1.1 value at 1.1 MHz referenced to black/white signal; 3.3 = 20 log (V0 at 4.4 MHz/V0 at 3.3 MHz); 3.3 value at 3.3 MHz referenced to colour carrier. 13. Response speed valid for a VIF input level range of 200 V up to 70 mV. 14. To match the AFC output signal to different tuning systems a current source output is provided. The test circuit is given in Fig.12. The AFC-steepness can be changed by the resistors at pin 23. 15. Depending on the ratio C/C0 of the LC resonant circuit of VCO (Q > 50; see note 3; C0 = Cint + Cext). 16. Source impedance: 2.3 k in parallel to 12 pF (SAW filter); fIF = 38.9 MHz. 17. The intercarrier output signal at pin 20 can be calculated by the following formula taking into account the video output signal at pin 21 (Vo video(p-p) = 1 V typical) as a reference:
V iSC ----------- ( dB ) + 6 dB 3 dB V iPC -------------------------------------------------------------20
1 V o ( rms ) = 1V ( p - p ) x ---------- x 10 22
1 with ---------- = correction term for RMS value, 22 V iSC ----------- ( dB ) = sound-to-picture carrier ratio at VIF input (pins 1 and 2) in dB, V iPC 6 dB = correction term of internal circuitry and 3 dB = tolerance of video output and intercarrier output amplitude Vo(rms). V iSC Example: SAW filter G1962 (sound shelf: 20 dB) ----------- = - 27 dB Vo(rms) = 32 mV typical. V iPC 18. Input level for second IF from an external generator with 50 source impedance. AC-coupled with 10 nF capacitor, fmod = 1 kHz, 27 kHz (54% FM deviation) of audio references. A VIF/SIF input signal is not permitted. Pins 8 and 28 have to be connected to positive supply voltage for minimum IF gain. S/N and THD measurements are taken at 50 s de-emphasis. Second IF input level 10 mV RMS. 19. Measured with an FM deviation of 27 kHz the typical AF output signal is 500 mV RMS (Rx = 0 ; see Fig.17). By using Rx = 470 the AF output signal is attenuated by 6 dB (250 mV RMS). For handling an FM deviation of more than 53 kHz the AF output signal has to be reduced by using Rx in order to avoid clipping (THD < 1.5%). For an FM deviation up to 100 kHz an attenuation of 6 dB is recommended with Rx = 470 . 20. The leakage current of the decoupling capacitor (2.2 F) should not exceed 1 A. 21. For all S/N measurements the used vision IF modulator has to meet the following specifications: Incidental phase modulation for black-to-white jump less than 0.5 degrees. Picture-to-sound carrier ratio; PC/SC = 13 dB; (transmitter). Sound shelf of VIF SAW filter: minimum 20 dB. 22. Measurements taken with SAW filter K6256 (Siemens) for vision and sound IF (sound shelf: 20 dB). Input level Vi SIF = 10 mV RMS, 27 kHz (54% FM deviation). 23. The PC/SC ratio at pins 1 and 2 is calculated as the addition of TV transmitter PC/SC ratio and SAW filter PC/SC ratio. This PC/SC ratio is necessary to achieve the S/N(W) values as noted. A different PC/SC ratio will change these values. 24. Measurements taken with SAW filter L9453 (Siemens) for AM sound IF (suppressed picture carrier). 25. The input voltage has to be V > 2.8 V, or open-circuit.

SOLDERING Plastic dual in-line packages BY DIP OR WAVE The maximum permissible temperature of the solder is 260 C; this temperature must not be in contact with the joint for more than 5 s. The total contact time of successive solder waves must not exceed 5 s. The device may be mounted up to the seating plane, but the temperature of the plastic body must not exceed the specified storage maximum. If the printed-circuit board has been pre-heated, forced cooling may be necessary immediately after soldering to keep the temperature within the permissible limit. REPAIRING SOLDERED JOINTS Apply a low voltage soldering iron below the seating plane (or not more than 2 mm above it). If its temperature is below 300 C, it must not be in contact for more than 10 s; if between 300 and 400 C, for not more than 5 s. Plastic small outline packages BY WAVE During placement and before soldering, the component must be fixed with a droplet of adhesive. After curing the adhesive, the component can be soldered. The adhesive can be applied by screen printing, pin transfer or syringe dispensing. Maximum permissible solder temperature is 260 C, and maximum duration of package immersion in solder bath is 10 s, if allowed to cool to less than 150 C within 6 s. Typical dwell time is 4 s at 250 C.
TDA9812
A modified wave soldering technique is recommended using two solder waves (dual-wave), in which a turbulent wave with high upward pressure is followed by a smooth laminar wave. Using a mildly-activated flux eliminates the need for removal of corrosive residues in most applications. BY SOLDER PASTE REFLOW Reflow soldering requires the solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the substrate by screen printing, stencilling or pressure-syringe dispensing before device placement. Several techniques exist for reflowing; for example, thermal conduction by heated belt, infrared, and vapour-phase reflow. Dwell times vary between 50 and 300 s according to method. Typical reflow temperatures range from 215 to 250 C. Preheating is necessary to dry the paste and evaporate the binding agent. Preheating duration: 45 min at 45 C. REPAIRING SOLDERED JOINTS (BY HAND-HELD SOLDERING
IRON OR PULSE-HEATED SOLDER TOOL)
Fix the component by first soldering two, diagonally opposite, end pins. Apply the heating tool to the flat part of the pin only. Contact time must be limited to 10 s at up to 300 C. When using proper tools, all other pins can be soldered in one operation within 2 to 5 s at between 270 and 320 C. (Pulse-heated soldering is not recommended for SO packages.) For pulse-heated solder tool (resistance) soldering of VSO packages, solder is applied to the substrate by dipping or by an extra thick tin/lead plating before package placement.
