FUNCTIONAL DESCRIPTION The TDA9809M is comprised of the functional blocks shown in Fig.1: * Vision IF amplifier and AGC detector * Tuner (TV/radio) and VIF AGC * Frequency Phase-Locked Loop (FPLL) detector * VCO, Travelling Wave Divider (TWD) and TV AFC * Video demodulator and amplifier * Intercarrier mixer * RIF amplifier and AGC detector * FM-PLL demodulator, level detector and radio AFC * Audio Frequency (AF) signal processing * Internal voltage stabilizer * Logic.
Vision IF amplifier and AGC detector The vision IF amplifier contains three AC-coupled differential amplifier stages. Each differential stage includes 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. The sync level of the video signal is therefore detected for negative video modulation. Tuner (TV/radio) and VIF AGC For TV operation, the AGC capacitor voltage is converted to an internal IF control signal and then 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 the tuner to be matched to the SAW filter in order to achieve the optimum IF input level. For FM radio operation, an AGC detector is provided to obtain some adjacent channel protection.

Preliminary specification
Single standard multimedia IF-PLL and FM radio demodulator
Frequency Phased-Locked Loop detector (FPLL) The VIF amplifier output signal is fed, via a limiting amplifier, to a frequency and phase detector. During acquisition, the frequency detector generates a DC current that is proportional to the difference in frequency between the input signal and the VCO signal. After frequency lock-in, the phase detector generates a DC current proportional to the phase difference between the input signal and the VCO signal. The DC current generated by the frequency or phase detector is converted to a DC voltage via the loop filter, which controls the VCO frequency. VCO, TWD and TV AFC The VCO operates with a resonance circuit (with L and C in parallel) at double the Picture Carrier (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 double the PC frequency is generated by the FPLL and fed via the loop filter to the first variable capacitor. This control voltage is amplified and converted into a current which represents the AFC output signal. At the centre frequency, the AFC output current is zero. The TWD divides the oscillator signal by 2 and generates two differential output signals with a 90 phase difference independent of frequency. Video demodulator and amplifier Video demodulation is realized by a multiplier designed for low distortion and wide bandwidth. The vision IF input signal and the `in-phase' signal of the travelling wave divider output are multiplied together. The demodulated output signal is fed to the video amplifier via an integrated low-pass filter used to attenuate the carrier harmonics. This is an operational amplifier with internal feedback and wide bandwidth. A low-pass filter is integrated to attenuate the carrier harmonics. 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 the sound trap output. Intercarrier mixer
TDA9809M
The intercarrier mixer is realized by a multiplier. The sound IF signal passes through the vision IF SAW filter and the composite IF signal is then fed to the intercarrier mixer. Here, the IF signal is multiplied by the 90 TWD output signal to convert the sound IF to the intercarrier frequency. By using this quadrature detection, the low frequency video signals are removed. The mixer output signal is fed, via a high-pass filter used to attenuate the video signal components, at output pin 10. RIF amplifier and AGC detector The radio IF amplifier amplifies the 10.7 MHz radio IF signal. This signal is supplied by the tuner and is fed to the RIF input (pin 4) via a matching circuit and a ceramic band-pass filter. This amplifier contains two stages. The first stage, a conventional 0 dB differential amplifier designed for optimal dynamic range, is followed by a switchable differential amplifier stage with a gain of 10 dB. Either the radio IF or the TV IF signal can be selected at the output (pin 10). The RIF output signal is fed via ceramic band-pass filters to the FM-PLL demodulator and the radio IF AGC detector. The AGC threshold is very high and is designed to obtain some adjacent channel protection. The AGC detector output is fed to the tuner AGC output stage (pin 12) to control the tuner. FM-PLL demodulator, level detector and radio AFC The FM-PLL demodulator consists of a limiter and an FM phase-locked loop. The 8-stage internally AC-coupled limiter amplifies and limits the TV FM sound intercarrier or the radio FM intermediate frequency signal prior to demodulation. The limiter is designed for high sensitivity and AM suppression with low DC offset and needs no external pins for DC coupling. Furthermore, the AF output signal can be force muted by connecting a resistor between pin 11 and ground. The soft mute function can be disabled by connecting a resistor between pin 11 and the power supply. See the application circuit in Fig.16.

Preliminary specification
Single standard multimedia IF-PLL and FM radio 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 on the AF voltage. The FM-PLL operates as an FM demodulator. The level detector detects, rectifies and amplifies the output signals from the first 5 limiter stages. These signals are then summed and the composite signal passed through a low-pass filter, followed by a 6 dB output amplifier. A DC voltage dependent on the limiter input level is generated for controlling the behaviour of the AF soft mute. The 6 dB output amplifier can be switched off via the control logic and the level detector output signal fed to pin 14. Furthermore, the steepness of the level detector output signal tracks that of the power supply voltage. The radio Automatic Frequency Control (AFC) stage is comprised of a 10.7 MHz phase shifting network, a phase detector (quadrature demodulator), a differential amplifier input stage (which receives the limiting amplifier output signal) and a current mode output stage. A ceramic resonator is used for phase shifting. This permits alignment-free operation. AF signal processing The AF signal processing stage consists of a pre-amplifier for the FM-PLL demodulator output signal, an AF source selector, a soft and forced mute stage with an integrated time constant and an AF post-amplifier. The FM demodulator output signal is pre-amplified by an operational amplifier (30 dB gain) with internal feedback, high gain and high common mode rejection. The feedback circuit, together with external capacitor CDEC connected to pin 9, keeps the DC level at the pre-amplifier output constant (2.3 V). An external resistor connected in series with CDEC provides a gain reduction capability. The low-pass filter characteristic (130 kHz bandwidth) of the amplifier reduces the harmonics of the IF signal at the sound signal output.
TDA9809M
Soft mute occurs when the internal level detector output voltage is lower than the mute threshold voltage at pin 8 (provided an external resistor is not connected between the limiter input, pin 11, and the supply voltage). The mute stage reduces the AF signal by 25 dB, with an internal time constant of approximately 7 ms. If a resistor is connected between pin 11 and ground (forced mute), the mute stage will reduce the AF signal by more than 70 dB with the same time constant. Otherwise, the AF signal will not be reduced. The AF post-amplifier, which was designed to include a rail-to-rail output stage, provides the required AF output level at pin 7. Internal voltage stabilizer The bandgap circuit generates a voltage of approximately 1.25 V internally, independent of supply voltage and temperature. A voltage regulator circuit connected to this voltage generates a constant 3.6 V which is used as an internal reference voltage. Logic The logic circuit detects the logic levels and threshold voltages at ports LP0 and LP2 and controls the internal functions as described in Table 2.

14. The intercarrier output signal at pin 10 can be calculated with the following formula using the video output signal at pin 13 (Vo(video)(p-p) = 1.1 V typical) as a reference:
V i ( SC ) ---------------- ( dB ) + 6 dB 3 dB V i ( PC ) ------------------------------------------------------------------20
1 V o ( rms ) = 1.1 V ( p - p ) x ---------- x 10 22
1 with ---------- = correction term for RMS value, 22 V i(SC) ------------- (dB) = sound-to-picture carrier ratio at VIF input (pins 1 and 2) in dB, V i(PC) 6 dB = correction term of internal circuitry and 3 dB = tolerance of video output and intercarrier output amplitude Vo(rms). V i(SC) Example: SAW filter G1962 (sound shelf: 20 dB) ------------- = - 27 dB V o(rms) = 32 mV (typ.) . V i(PC) 15. 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 reference. A VIF/SIF input signal is not permitted. Pin 5 has to be connected to the positive supply voltage for minimum IF gain. S/N and THD measurements are taken at 50 s (75 s at M standard) de-emphasis (modulator pre-emphasis has to be activated). The FM demodulator steepness Vo(AF)/fAF is positive. a) Second IF input level 10 mV (RMS). 16. Measured with an FM deviation of 27 kHz, the typical AF output signal is 500 mV (RMS) (Rx = 0 ). By using Rx = 680 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 = 680 . 17. The leakage current of the decoupling capacitor (2.2 F) should not exceed 1 A. 18. For all S/N measurements, the vision IF modulator used must 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). 19. The PC/SC1 ratio at pins 1 and 2 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. 20. Measurements taken with SAW filter G1962 (sound shelf: 20 dB) for vision and sound IF. 21. The RIF amplifier output (pin 10) must be connected to a multistandard application ceramic filter for 5.5, 6.0 and 10.7 MHz. This total load constitutes an impedance of 250 . 22. d3 tested using two signals with frequencies of f1 = 10.5 MHz and f2 = 10.7 MHz, and with a level of Vi(4)(max)(rms) for each signal. d3 is the ratio of the intermodulation product at 10.3 MHz to the output level of Vi(4)(max)(rms). 23. The control steepness of the radio AFC detector is dependent on the characteristic of the ceramic resonator, pin 18. The figure given here will be obtained when applying a typical resonator of the type CDA 10.7 MC1-A (Murata). The spread of the control steepness depends on the spread of the ceramic resonator characteristic (see Fig.11).

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 SSOP 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 is not recommended for SSOP packages. This is because of the likelihood of solder bridging due to closely-spaced leads and the possibility of incomplete solder penetration in multi-lead devices.
TDA9809M
If wave soldering cannot be avoided, the following conditions must be 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 and must incorporate solder thieves at the downstream end. Even with these conditions, only consider wave soldering SSOP packages that have a body width of 4.4 mm, that is SSOP16 (SOT369-1) or SSOP20 (SOT266-1). 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.
