VIF-PLL with QSS-IF and
dual FM-PLL demodulator

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 takeover 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 the sync level of the video signal is detected.

Frequency Phase Locked Loop (FPLL) detector

TDA9813T

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 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. 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. 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.

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.

VCO, travelling wave divider 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
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. 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.

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 FM carriers) 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 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.

Philips Semiconductors Preliminary specification

VIF-PLL with QSS-IF and
dual FM-PLL demodulator

FM detectors

Each 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.

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 kΩ resistor from
pin 14 to +V

Furthermore the AF output signals can be muted by
connecting a resistor between the limiter inputs pin 14 or
pin 15 and ground.

(see Fig.11).

TDA9813T

Internal voltage stabilizer and

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

1

the

⁄2VP 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 1⁄2VP an internal
start-up circuit is added.

⁄2VP-reference

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 FM or
mute state, controlled by the mute switching voltage.

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 = 180 kHz (natural frequency fn= 15 kHz; damping factor d ≈ 5; calculated with sync level within
gain control range). Resonance circuit of VCO: Q0> 50; C

= 8.2 pF ±0.25 pF; C

ext

≈ 8.5 pF (loop voltage

int

approximately 2.7 V).

4. Temperature coefficient of external LC-circuit is equal to zero.

5. V

= 10 mV (RMS); ∆f = 1 MHz (VCO frequency offset related to picture carrier frequency); white picture

6. V

7. Offset current measured between pin 5 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 (V25=VP).

8. Measurements taken with SAW filter G3962 (sound carrier suppression: 40 dB); loop bandwidth BL = 180 kHz:
a) Modulation VSB; sound carrier off; f
b) Ssound carrier on; SIF SAW filter L9453; f

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 Ω resistor must be connected from
output to input (from pin 18 to pin 19).

10. The leakage current of the AGC capacitor should not exceed 1 µA. 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 8). B = 5 MHz weighted
in accordance with

“CCIR 567”

14. 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.

15. Depending on the ratio ∆C/C0 of the LC resonant circuit of VCO (Q0> 50; see note 3; C0=C

16. Source impedance: 2.3 kΩ in parallel to 12 pF (SAW filter); fIF= 38.9 MHz.

17. Input level for second IF from an external generator with 50 Ω source impedance. AC-coupled with 10 nF capacitor,
f

= 1 kHz, 27 kHz (54% FM deviation) of audio references. A VIF/SIF input signal is not permitted. Pins 6 and 25

mod

have to be connected to positive supply voltage for minimum IF gain. S/N and THD measurements are taken at 50 µs
de-emphasis. The not tested FM-PLL has to be locked to an unmodulated carrier.

a) Second IF input level 10 mV (RMS).

18. Measured with an FM deviation of 27 kHz the typical AF output signal is 500 mV RMS (Rx=Ry=0Ω; see Fig.11).
By using Rx=Ry= 470 Ω 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 Ω.

19. The leakage current of the decoupling capacitor (2.2 µF) should not exceed 1 µA.

20. 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.11). 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.

21. 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 sinewave black-to-white video modulation.

c) Picture-to-sound carrier ratio; PC/SC1= 13 dB; (transmitter).

22. Measurements taken with SAW filter G3962 (Siemens) for vision IF (suppressed sound carrier) and G9350
(Siemens) for sound IF (suppressed picture carrier). Input level V

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.

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

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.

(order code 9398 652 90011).

TDA9813T

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.

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.
