Multistandard VIF-PLL with QSS-IF and dual FM-PLL/AM demodulator
FUNCTIONAL DESCRIPTION The integrated circuit comprises the functional blocks as shown in Fig.1: * Vision IF amplifier * Tuner and VIF-AGC * Frequency Phase Locked Loop detector (FPLL) * VCO, Travelling Wave Divider (TWD) and AFC * Video demodulator and amplifier * Video buffer * SIF amplifier and AGC * Single reference QSS mixer * AM demodulator * FM-PLL demodulator * Internal voltage stabilizer and 12VP-reference. 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 takeover point can be adjusted. This allows the tuner and the SAW 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.
TDA9814T
Frequency Phase Locked Loop 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 (TWD) and AFC 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 free-running frequency to actually double the PC frequency is generated by the frequency-phase detector (FPLL) and fed via the loop filter to the first variable capacitor. 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 accent standard) by activating an additional internal capacitor. This is achieved by using the L accent switch. In this event the second variable capacitor can be controlled by a variable resistor at the L accent switch for setting the VCO centre frequency to the required L accent value. At centre frequency the AFC output current is equal to zero. The oscillator signal is divided-by-two with a TWD which generates two differential output signals with a 90 degree phase difference independent of the frequency.

Multistandard VIF-PLL with QSS-IF and dual FM-PLL/AM demodulator
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 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 or FM carriers) and controls the SIF amplifier to provide a constant SIF signal to the AM demodulator and single reference QSS mixer. 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. In FM mode this reaction time is also set to `fast' controlled by the standard switch. Single reference QSS mixer
TDA9814T
The single reference QSS mixer is realized by a multiplier. The SIF amplifier output signal is fed to the single reference QSS 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 to the output pin 17. With this system a high performance hi-fi stereo sound processing can be achieved. 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-PLL demodulator Each FM-PLL demodulator 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. The second limiter is extended with an additional level detector consisting of a rectifier and a comparator. By means of this the AF2 signal is set to mute and the PLL VCO is switched off, if the intercarrier signal at pin 14 is below 1 mV (RMS) in order to avoid false identification of a stereo decoder. Note that noise at pin 14 disables the mute state (at low SIF input signal), but this will not lead to false identification. This `auto-mute' function can be disabled by connecting a 5.6 k resistor from pin 14 to VP (see Fig.13). Furthermore the AF output signals can be muted by connecting a resistor between the limiter inputs pin 14 or pin 15 and ground.

Multistandard VIF-PLL with QSS-IF and dual FM-PLL/AM demodulator
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: 1. 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. An additional DC control circuit is implemented to keep the DC level constant, independent of process spread. 2. 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 or mute state, controlled by the standard switching voltage and the mute switching voltage.

TDA9814T
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.

Notes to the characteristics 1. 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 = 75 kHz (natural frequency fn = 11 kHz; damping factor d 3.5; 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. Measurements taken with SAW filter G3962 (sound carrier suppression: 40 dB); loop bandwidth BL = 75 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. 8. 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 18 to pin 19). 9. 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. 10. S/N is the ratio of black-to-white amplitude to the black level noise voltage (RMS value, pin 8). B = 5 MHz weighted in accordance with "CCIR 567". 11. The intermodulation figures are defined: V 0 at 4.4 MHz 1.1 = 20 log ------------------------------------- + 3.6dB; 1.1 value at 1.1 MHz referenced to black/white signal; V 0 at 1.1 MHz V 0 at 4.4 MHz 3.3 = 20 log ------------------------------------- ; 3.3 value at 3.3 MHz referenced to colour carrier. V 0 at 3.3 MHz 12. Response speed valid for a VIF input level range of 200 V up to 70 mV. 13. To match the AFC output signal to different tuning systems a current source output is provided. The test circuit is given in Fig.7. The AFC-steepness can be changed by the resistors at pin 20. 14. Depending on the ratio C/C0 of the LC resonant circuit of VCO (Q0 > 50; see note 3; C0 = Cint + Cext). 15. Source impedance: 2.3 k in parallel to 12 pF (SAW filter); fIF = 38.9 MHz.

16. 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 6 and 25 have to be connected to positive supply voltage for minimum IF gain. S/N and THD measurements are taken at 50 s de-emphasis. The not tested FM-PLL has to be locked to an unmodulated carrier. a) Second IF input level 10 mV RMS. 17. Measured with an FM deviation of 27 kHz the typical AF output signal is 500 mV RMS (Rx = Ry = 0 ; see Fig.13). By using Rx = Ry = 470 the AF output signal is attenuated by 6 dB (250 mV RMS) and adapted to the stereo decoder family TDA9840. For handling an FM deviation of more than 53 kHz the AF output signal has to be reduced by using Rx and Ry 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 = Ry = 470 . 18. The leakage current of the decoupling capacitor (2.2 F) should not exceed 1 A. 19. In the event of activated auto mute state the second FM-PLL oscillator is switched off, if the input signal at pin 14 is missing or too weak (see Fig.13). In the event of switching the second FM-PLL oscillator on by the auto mute stage an increased DC jump is the consequence. Note, that noise at pin 14 disables the mute state (at low SIF input signal), but this will not lead to false identification of the used stereo decoder family TDA9840. 20. For all S/N measurements the used vision IF modulator has to meet the following specifications: a) Incidental phase modulation for black-to-white jump less than 0.5 degrees. b) QSS AF performance, measured with the television-demodulator AMF2 (audio output, weighted S/N ratio) better than 60 dB (deviation 27 kHz) for 6 kHz sine wave black-to-white video modulation. c) Picture-to-sound carrier ratio; PC/SC1 = 13 dB (transmitter). 21. Measurements taken with SAW filter G3962 (Siemens) for vision IF (suppressed sound carrier) and G9350 (Siemens) for sound IF (suppressed picture carrier). Input level Vi SIF = 10 mV RMS, 27 kHz (54% FM deviation). 22. 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. 23. Measurements taken with SAW filter L9453 (Siemens) for AM sound IF (suppressed picture carrier). 24. The input voltage has to be Vi > 2.8 V or open-circuit.

SOLDERING Introduction There is no soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and surface mounted components are mixed on one printed-circuit board. However, wave soldering is not always suitable for surface mounted ICs, or for printed-circuits with high population densities. In these situations reflow soldering is often used. This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in our "IC Package Databook" (order code 9398 652 90011). Reflow soldering Reflow soldering techniques are suitable for all SO packages. Reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement. Several techniques exist for reflowing; for example, thermal conduction by heated belt. Dwell times vary between 50 and 300 seconds depending on heating 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 minutes at 45 C. Wave soldering Wave soldering techniques can be used for all SO packages if the following conditions are observed: * A double-wave (a turbulent wave with high upward pressure followed by a smooth laminar wave) soldering technique should be used. * The longitudinal axis of the package footprint must be parallel to the solder flow. * The package footprint must incorporate solder thieves at the downstream end.
TDA9814T
During placement and before soldering, the package must be fixed with a droplet of adhesive. The adhesive can be applied by screen printing, pin transfer or syringe dispensing. The package can be soldered after the adhesive is cured. Maximum permissible solder temperature is 260 C, and maximum duration of package immersion in solder is 10 seconds, if cooled to less than 150 C within 6 seconds. Typical dwell time is 4 seconds at 250 C. A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. Repairing soldered joints Fix the component by first soldering two diagonallyopposite end leads. Use only a low voltage soldering iron (less than 24 V) applied to the flat part of the lead. Contact time must be limited to 10 seconds at up to 300 C. When using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 C.
