FUNCTIONAL DESCRIPTION The integrated circuit comprises the functional blocks as shown in Fig.1: * Vision IF amplifier and VIF AGC detector * Tuner AGC * Frequency Phase Locked Loop detector (FPLL) * VCO, Travelling Wave Divider (TWD) and AFC * Video demodulator and amplifier * SIF amplifier and SIF AGC * Single reference QSS mixer * AM demodulator * FM-PLL demodulator * AF (Audio Frequency) signal processing * Internal voltage stabilizer. Vision IF amplifier and VIF AGC detector The vision IF amplifier consists of three AC-coupled differential amplifier stages. Each differential stage comprises a feedback network controlled by emitter degeneration. The AGC detector generates the required VIF gain control voltage for constant video output by charging/discharging the AGC capacitor. 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. Tuner AGC The AGC capacitor voltage is converted to an internal IF control signal, and is fed to the tuner AGC to generate the tuner AGC output current at pin TAGC (open-collector output). The tuner AGC takeover point can be adjusted at pin TADJ. This allows to match the tuner to the SAW filter in order to achieve the optimum IF input level. 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 1997 May 12 6
TDA9817; TDA9818
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. At centre frequency the AFC output current is equal to zero. For TDA9818: 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. The oscillator signal is divided by 2 with a 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 at Vo(vid) is 1.1 V (p-p) for nominal vision IF modulation, in order to achieve 1 V (p-p) at sound trap output.

SIF amplifier and SIF 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 signal (average level of AM or FM carrier) and controls the SIF amplifier to provide a constant SIF signal to the AM demodulator and single reference QSS mixer. At L standard (AM sound) 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 always `fast'. Single reference QSS mixer 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 12. With this system a high performance hi-fi stereo sound processing can be achieved. For a simplified application without a sound IF SAW filter the single reference QSS mixer can be switched to the intercarrier mode by connecting pin 24 to ground. In this mode the sound IF passes the vision IF SAW filter and the composite IF signal is fed to the single reference QSS mixer. This IF signal is multiplied with the 90 degree TWD output signal for converting the sound IF to intercarrier frequency. This composite intercarrier signal is fed to the output pin 12, too. By using this quadrature detection, the low frequency video signals are removed. 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 The FM-PLL demodulator consists of a limiter and an FM-PLL. The limiter provides the amplification and limitation of the FM sound intercarrier signal. The result is high sensitivity and AM suppression. The amplifier
TDA9817; TDA9818
consists of 7 stages which are internally AC-coupled in order to minimize the DC offset. Furthermore the AF output signal can be muted by connecting a resistor between the limiter input pin 13 and ground. 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. AF signal processing The AF amplifier consists of two parts: 1. The AF pre-amplifier 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 pin 9 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. 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 de-emphasis or mute state, controlled by the standard switching voltage and the mute switching voltage. Internal voltage stabilizer 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.

Notes to the characteristics 1. Values of video and sound parameters are decreased at VP = 4.5 V.
TDA9817; TDA9818
2. This parameter is not tested during production and is only given as an application information for designing the television receiver. 3. Loop bandwidth BL = 70 kHz (natural frequency fn = 12 kHz; damping factor d 3; 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)(rms) = 10 mV; f = 1 MHz (VCO frequency offset related to picture carrier frequency); white picture video modulation. 6. Vi IF signal for nominal video signal. 7. 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. 8. S/N is the ratio of black-to-white amplitude to the black level noise voltage (RMS value, pin 16). B = 5 MHz weighted in accordance with "CCIR 567". 9. The intermodulation figures are defined: V 0 at 4.4 MHz 1.1 = 20 log ------------------------------------- + 3.6 dB ; 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 10. Measurements taken with SAW filter K3953 (sound carrier suppression: 40 dB); loop bandwidth BL = 70 kHz: a) Modulation VSB; sound carrier off; fvideo > 0.5 MHz. b) Sound carrier on; SIF SAW filter K9453; fvideo = 10 kHz to 10 MHz. 11. Response speed valid for a VIF input level range of 200 V up to 70 mV. 12. 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 17. 13. Depending on the ratio C/C0 of the LC resonant circuit of VCO (Q0 > 50; see note 3; C0 = Cint + Cext). 14. Source impedance: 2.3 k in parallel to 12 pF (SAW filter); fIF = 38.9 MHz. 15. Without using an SIF SAW filter the mixer can be switched to intercarrier mode by connecting pin 23 and/or pin 24 to ground. In this mode the SIF passes the VIF SAW filter and IF intercarrier levels are depending on the sound shelf of the VIF SAW filter. The intercarrier output signal at pin 12 can be calculated by the following formula taking into account the video output signal at pin 16 (Vo(video)(p-p) = 1.1 V typical) as a reference:

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 5 and 4 have to be connected to positive supply voltage for minimum IF gain. S/N and THD measurements are taken at 50 s de-emphasis at pin 9 (modulator pre-emphasis has to be activated). The FM demodulator steepness Vo(AF)/fAF is positive. 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 = 0 ). By using Rx = 470 the AF output signal is attenuated by 6 dB (250 mV RMS). For handling a frequency 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 . 18. The leakage current of the decoupling capacitor (2.2 F) should not exceed 1 A. 19. 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). 20. The PC/SC1 ratio is calculated as the addition of TV transmitter PC/SC1 ratio and SAW filter PC/SC1 ratio. This PC/SC1 ratio is necessary to achieve the S/NW values as noted. A different PC/SC1 ratio will change these values. 21. Measurements taken with SAW filter K3953 for vision IF (suppressed sound carrier) and K9453 for sound IF (suppressed picture carrier). Input level Vi(SIF)(rms) = 10 mV, 27 kHz (54% FM deviation). 22. Measurements taken with SAW filter G1962 (sound shelf: 20 dB) for vision and sound IF. Pin 23 and/or pin 24 has to be connected to ground for switching the single reference QSS mixer to intercarrier mode. 23. Measurements taken with SAW filter K9453 (Siemens) for AM sound IF (suppressed picture carrier).

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). Soldering by dipping or by wave The maximum permissible temperature of the solder is 260 C; solder at this temperature must not be in contact with the joint for more than 5 seconds. The total contact time of successive solder waves must not exceed 5 seconds. DEFINITIONS Data sheet status Objective specification Preliminary specification Product specification Limiting values
TDA9817; TDA9818
The device may be mounted up to the seating plane, but the temperature of the plastic body must not exceed the specified maximum storage temperature (Tstg max). 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 (less than 24 V) to the lead(s) of the package, below the seating plane or not more than 2 mm above it. If the temperature of the soldering iron bit is less than 300 C it may remain in contact for up to 10 seconds. If the bit temperature is between 300 and 400 C, contact may be up to 5 seconds.
