Single standard VIF-PLL with QSS-IF and FM-PLL demodulator
FUNCTIONAL DESCRIPTION
The integrated circuit comprises the functional blocks as shown in Fig.1:
1. Vision IF amplifier and VIF AGC detector
2. Tuner AGC
3. Frequency Phase Locked Loop (FPLL) detector
4. Voltage Controlled Oscillator (VCO), Travelling Wave Divider (TWD) and AFC
5. Video demodulator and amplifier
6. SIF amplifier and SIF AGC
7. Single reference QSS mixer
8. FM-PLL demodulator
9. Audio Frequency (AF) signal processing
10. 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 synchronisation level of the video signal is detected.
TDA9808
VCO, Travelling Wave Divider (TWD) and 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 frequency-phase detector of the 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 the 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.
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.
The demodulator output signal is fed to the video amplifier via an integrated low-pass filter for attenuation of the carrier harmonics. 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. The video output signal at pin V modulation. Noise clipping is provided.
is 1.35 V (p-p) for nominal vision IF
o(vid)
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 (FPLL) detector
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 the frequency detector or the phase detector is converted to a DC voltage via the loop filter, which controls the VCO frequency.
1997 Jun 13 6
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 FM carrier) and controls the SIF amplifier to provide a constant SIF signal to the single reference QSS mixer.
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 filter for attenuation of the video signal components to the output pin 10. With this system a high performance hi-fi stereo sound processing can be achieved.

Philips Semiconductors Preliminary specification
Single standard VIF-PLL with QSS-IF and FM-PLL demodulator
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 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 11 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
TDA9808
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 FM or mute state, controlled by 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.
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 10. An additional DC control circuit is implemented to keep the DC level constant, independent of process spread.

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 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; C

7. Offset current measured between pin 4 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 (V17=VP).
8. The leakage current of the AGC capacitor should not exceed 100 nA at M, N standard. Larger currents will increase the tilt.
9. S/N is the ratio of black-to-white amplitude to the black level noise voltage (RMS value, pin 9). B = 5 MHz weighted in accordance with

12. Response speed valid for a VIF input level range of 200 µVupto70mV.
13. To match the AFC output signal to different tuning systems a current source output is provided. The test circuit is given in Fig.10. The AFC-steepness can be changed by the resistors at pin 13.

have to be connected to positive supply voltage for minimum IF gain. S/N and THD measurements are taken at 75 µs de-emphasis (modulator pre-emphasis has to be activated). The FM demodulator steepness V positive.
a) Second IF input level 10 mV RMS.
17. Measured at de-emphasis circuitry with an FM deviation of 25 kHz (f 500 mV RMS (Rx=0Ω). 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 (22 µF) should not exceed 1 µA.
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 25 kHz) for 6 kHz sine wave black-to-white video modulation.
c) Picture-to-sound carrier ratio; PC/SC1= 7 dB (transmitter).
20. The PC/SC1 ratio is calculated as the addition to TV transmitter PC/SC1 ratio and SAW filter PC/SC1 ratio. This PC/SC1 ratio is necessary to achieve the S/N values.

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”
DIP
SOLDERING BY DIPPING OR BY WA VE 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.
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 (T printed-circuit board has been pre-heated, forced cooling may be necessary immediately after soldering to keep the temperature within the permissible limit.
R
EPAIRING 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.
SO
REFLOW SOLDERING Reflow soldering techniques are suitable for all SO
packages.

). If the
stg max
TDA9808
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.
AVE SOLDERING
W 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.
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.
R
EPAIRING 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.
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.
